I get a rather weird reproducible error that crashes Julia in REPL and freezes it in Jupyter. The error happens whenever I use `include` followed by `workspace` then `include` again. I am using v0.50.

The code I run is:

```julia
include("test_prep.jl")
#Some tests and debugging
workspace()
include("test_prep.jl")

```

Here is the content of `test_prep.jl`:

```julia
include("VTKDataTypes\\src\\VTKDataTypes.jl")
include("VTKDataIO\\src\\VTKDataIO.jl")

using VTKDataTypes
using VTKDataIO

```

Here is the content of `VTKDataTypes.jl`:

```julia

module VTKDataTypes

using WriteVTK

include("vtkcelltypes.jl")
include("types.jl")
include("utils.jl")
include("validation.jl")
include("typeconversion.jl")

export AbstractVTKData, AbstractStaticVTKData, AbstractTimeSeriesVTKData
export AbstractVTKSimpleData, AbstractVTKMultiblockData
export AbstractVTKUnstructuredData, AbstractVTKStructuredData, AbstractVTKRectilinearData
export VTKUnstructuredData, VTKStructuredData, VTKRectilinearData, VTKUniformRectilinear, VTKImageData
export VTK_CELL_TYPE, POINT_CELLS, LINE_CELLS, FACE_CELLS, VOLUME_CELLS
export LINEAR_CELLS, QUADRATIC_CELLS, CUBIC_CELLS, HIGHER_ORDER_CELLS, HIGHER_ORDER_PARAMETRIC_CELLS, SPECIAL_CELLS
export promote_rule, size, length, getindex, endof, start, next, done
export same_geometry, ==, same_ordered_geometry, same_geometry_shape, same_data_shape, coherent
export extents, dim, num_of_points, num_of_cells, num_of_point_vars, num_of_cell_vars
export cell_type, cell_connectivity, has_var, var_dim, vtk_cell_type_name, is_homogeneous, filter_cells!
export keep_volume_cells_only!, keep_face_cells_only!, get_cell_ids, get_lowest_index, get_highest_index
export is_valid_cell, add_new_cell, remove_cell!, add_point_id_offset!, append!, append
export num_of_blocks, insert_new_block!, remove_block!, timespan, num_of_timesteps, insert_timed_data!
export remove_timed_data!, remove_timed_data!, is_valid, convert

end

```

Here is the content of `VTKDataIO.jl`:

```julia
module VTKDataIO

using VTKDataTypes
using WriteVTK
using PyCall
@pyimport paraview.simple as pv
@pyimport paraview.servermanager as ps
@pyimport paraview.numpy_support as pnp

include("paraviewreaders.jl")
include("vtkwriters.jl")

export read_vtk, write_to_file

end

```

Finally here is the longest bit, the error. Anyone knows what I am doing wrong, if anything at all?

There was a recent thread that, as far as I remember, basically said “don’t use workspace”.

Would the following work instead? Basically a gutted-out workspace that does not save the last module.

```julia
function cleanworkspace()
    lastbase = Core.Main.Base
    ccall(:jl_new_main_module, Any, ())
    newmain = Core.Main
    ccall(:jl_add_standard_imports, Void, (Any,), newmain)
    eval(newmain, Expr(:toplevel, :(const Base = $(Expr(:quote, lastbase)))))
    empty!(Base.package_locks)
    nothing
end

```

_EDIT_ the original was overenthusiastic and axed `Base`.

FWIW, this still breaks if you are using `PyPlot` (which has always been a problem with `workspace()`).

I get around this by putting most of my code into modules and not introducing the modules into the REPL scope (ie don’t use `using` at top level scope). Basically what is described here: [https://docs.julialang.org/en/stable/manual/workflow-tips/](https://docs.julialang.org/en/stable/manual/workflow-tips/)

If I really need the REPL for debugging purposes I will load the modules and then restart `julia` when I’m done with the debugging/editing and want to test my code again.

Another option if you want to use code in the REPL without `using MyModule` is to qualify the methods, ie: `MyModule.MyMethod()`

When I drop `workspace`, and I change a function definition, I get this warning `WARNING: using VTKDataIO.read_vtk in module Main conflicts with an existing identifier.` and it keeps on using the old function definition.

Surprisingly, when I qualify the function call with the module name, it uses the new definition.

Edited to add: Or I guess not so suprisingly, but it seems that simply redefining a module and calling `using` again does not redefine all the functions already in the main scope, but the functions in the module’s scope are actually the new ones, which is potentially a bug.

EDA: But then I guess this non-functionality was…added so that any sub-module does not get defined multiple times if used by multiple modules by running `using` on the final version of each of those modules in the actual program.

Some / much of this has changed in Julia 0.6.

Thanks! It works. I added it to my juliarc file.  
Devs, could we get this permanently?

See [updated version](https://github.com/tpapp/TKPappKitchenSink.jl/blob/master/src/utilities.jl#L88), which now also loads `~/.juliarc.jl`.
