I meant something like this
julia> macro mymacro(a,b,c)
println(c)
end
julia> @mymacro("aaa", ("bbb", "ccc")...)
ERROR: wrong number of arguments
which works fine for functions
julia> function myfunc(a,b,c)
println(c)
end
myfunc (generic function with 1 method)
julia> myfunc("aaa", ("bbb", "ccc")...)
