[julia-users] Macro with varargs

[Kuba Roth]

This is my first  time writing macros in Julia. I've read related docs but 
could not find an example which works with the arbitrary number of arguments.
So in my example below the args... works correctly with string literals but for 
the passed variables it returns their names and not the values. I'm pretty sure 
this is a newbie mistake and much appreciate any comments.
Thank you.

macro echo (args...)
     :(for x in $args
       print(x, " ")
       end)
end

julia> @echo "AAA" "VVV" 1
AAA VVV 1

julia> testB = "BBB"
"BBB"
julia> testC = "CCC"
"CCC"
julia> @echo testB testC
testB testC
