Appreciate guidance on whether I need to clear the workspace everytime I change my module and I need to rerun (including recompiling other modules like Gadfly):

```julia
workspace()
using Gadfly
# using LastMain.Gadfly # most times this can be used unless Julia crashes
reload("dlp.jl") # this is my module I'm debugging
using dlp #this is my module I'm debugging
fName="jTestData/Reduced_Sweeping_Test.dlp"
o=dlp.Read(fName) # call to module to debug

```

This doesn’t work; `using` and `reload` are incompatible (see the [workflow tips](http://docs.julialang.org/en/release-0.5/manual/workflow-tips/)). However, [ClobberingReload.jl](https://github.com/cstjean/ClobberingReload.jl) solves that.

```julia
using ClobberingReload
using dlp

... change dlp's source code

creload("dlp")

... changes took place, no need to call workspace()

```

BTW, quote your code in triple-backquote ( ` ) to make it look nicer on this forum.
