Is this a bug (related to scoping / nested macros)?

[Marius Millea]

I can't figure out why this doesn't work:

julia> macro outer()
           quote
               macro inner()
               end
               @inner
           end
       end


julia> @outer
ERROR: UndefVarError: @inner not defined

Could it be a bug (I'm on 0.5) or am I missing something about how macros work?

It's not a bug, the whole expression needs to be expand we before it's evaluate so the macro is not defined yet
