Varargs inside macros swallow keyword arguments

[nalimilan]

Macros with complex uses of varargs and keyword arguments can give really weird results. In the following, the keyword argument y shouldn't be passed to g(), nor passed twice to f(), and using , or ; shouldn't make any difference.

julia> macro test(d, x...; y=0)
           esc(:(f(g($d, $(x...)), $(x...); y=$y)))
       end
@test (macro with 1 method)

julia> macroexpand(:(@test(1, 2, 3; y=4)))
:(f(g(1,2,3; y=4),1,2,3; y=0))

julia> macroexpand(:(@test(1, 2, 3, y=4)))
:(f(g(1,2,3,y=4),2,3,y=4; y=0))

This is not related to Varargs since I don't think you can pass any kw argument to a macro in general, they are all passed as expressions, i.e. Expr(:kw) and Expr(:parameters).

Thanks. Are there any plans to allow passing keyword arguments to macros? I have a case in which it would have been useful.
