ERROR: local variable #self# not defined

[tehrengruber]

So I was just working/trying to add support for removing declarations from the current compiler instance in CXX (Keno/you and I talking about this missing feature briefly yesterday). While doing so I needed to get some deeper understanding about CXX and stumbled upon this bug in Gallium. I sadly have no further information about the reason for it so here is how you can reproduce the error:

julia> using Cxx

I should mention that this bug is probably not related to Cxx in any way, but it was the first time it occured to me.

[Keno]

Yes, it's not. I essentially know how to fix it. Will get to it soon.
