"Type aliases" like X{T} = Y{T, S} are not handled

[tkf]

It seems that "type aliases" are not handled correctly at the moment:

julia> solve(:(X{T} = Y{T, S}))
:((@global X){@global T} = (@global Y){@global T, @global S})

I suppose the result should be

:((@global X){@T} = (@global Y){@T, @global S})

?

Yes, it's a bit complex, and requires more efforts to match the correct semantics.
I remembered you've sent the link of the scheme file(julia-syntax.scm) which implements the syntax analysis, but it's in quite a huge scale so I cannot reach the same functions immediately.

Yes, Julia language is a huge target and I admire your courage to implement JuliaVariables.jl :)

I'm not familiar with compiler/language things, but I thought this analysis is done while lowering. But I'm not sure.
