[julia-users] ccall and type definition in a macro

[juliatylors]

Hi,

I am having the following problem. Here is my code:
julia> macro myname(arg)
              typname = esc(arg)
              privtypname = esc(symbol(string("priv",arg)))
              code = quote
                  typealias $(typname) ccall( (:clock, "libc"), Int32, ())
                  type $privtypname
                      a
                  end
              end
              return code
       end

the error i get is : *ERROR: error compiling anonymous: type definition not 
allowed inside a local scope*

Can anyone tell me what is wrong? The macroexpand code seems normal:

julia> macroexpand(:(@myname goox))
quote  # none, line 5:
    typealias goox ccall((:clock,"libc"),Int32,()) # none, line 6:
    type privgoox # none, line 7:
        a
    end
end

thanks
