I’m working on [https://github.com/GiovineItalia/Compose.jl/pull/282](https://github.com/GiovineItalia/Compose.jl/pull/282) and I ran into a change in how eval behaves on v0.6 to v0.7 and AFAIK the change isn’t documented.

on v0.6

```julia
julia> ex = Expr(:import, Symbol("Fontconfig"))
:(import Fontconfig)

julia> @eval $ex
ERROR: ArgumentError: Module Fontconfig not found in current path.
Run `Pkg.add("Fontconfig")` to install the Fontconfig package.
Stacktrace:
 [1] _require(::Symbol) at ./loading.jl:435
 [2] require(::Symbol) at ./loading.jl:405
 [3] eval(::Module, ::Expr) at ./sysimg.jl:23

julia> import Fontconfig
ERROR: ArgumentError: Module Fontconfig not found in current path.
Run `Pkg.add("Fontconfig")` to install the Fontconfig package.
Stacktrace:
 [1] _require(::Symbol) at ./loading.jl:435
 [2] require(::Symbol) at ./loading.jl:405

```

while on v0.7.0-DEV.4958 (2 day old master)

```julia
julia> ex = Expr(:import, Symbol("Fontconfig"))
:(import Fontconfig)

julia> @eval $ex

julia> import Fontconfig
ERROR: ArgumentError: Module Fontconfig not found in current path.
Run `Pkg.add("Fontconfig")` to install the Fontconfig package.
Stacktrace:
 [1] require(::Module, ::Symbol) at ./loading.jl:864

```

`Fontconfig` isn’t installed in either case. I don’t see why there is a discrepancy between `@eval`ing an import statement and running the actual `import` statement?

I’m not sure if this a bug at this point, but I’m thinking of posting it on the github issue tracker

Not sure why it doesn’t throw an error, but the syntax is wrong. On v0.7, it should be:

```julia
eval(Expr(:import, Expr(:., :Fontconfig)))

```

Although probably easier and better to just to load the module directly:

```julia
local FC = Base.require(@ __MODULE__ , :Fontconfig)

```

Or even better, to use Requires.jl to do the work for you at runtime
