Fields of struct are treated as globals

[tkf]

Hi, thanks for a super useful package. Unfortunately, I think I find a bug

julia> solve(:(struct S
           x
       end))
:(struct @global S
      #= REPL[11]:2 =#
      @global x
  end)

I suppose @global x is wrong?

Yes, I didn't treat struct yet.
A bit curious, Is this necessary? I think the scope of struct is simple so we can treat them separately.

Yeah, I think I can skip fields while processing solved tree. But I thought it would be nice if I can just blindly look for ScopedVar.
