here is a bug I just found.

julia> function foo()
       t = :doesnt_exist
       @exfiltrate
       end
foo (generic function with 1 method)

julia> foo()
ERROR: UndefVarError: doesnt_exist not defined

Hey, just as a heads up: While getting Infiltrator ready for a 1.0 release I also added an @exfiltrate macro (ref JuliaDebug/Infiltrator.jl#35).
It works slightly different than Exfiltrators, but the idea is the same.

Thank you for Exfiltrator! This package is beautiful and is making debugging Julia so much easier for me. I have encountered a problem though that where as the basic Main.@exfiltrate works fine from within package functions, the expanded syntax Main.@exfiltrate VARS doesn't seem to do anything. It does work fine in test functions outside of a package.

Here's an example where it does nothing:

using Exfiltrator

module MyMod

function f(x)
    Main.@exfiltrate vars
    2x
end

end

MyMod.f(1)

And then there is no vars in the Main workspace.

I get this error inside a function. I don't have diff as a local variable at all, which is very weird.
