           Summary: Typesefe variadic functions don't work at compile time
           Product: D
           Version: 2.013
          Platform: PC
        OS/Version: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla at digitalmars.com
        ReportedBy: bartosz at relisoft.com


The following doesn't compile:

string foo (string [] a...)
{
    string result = "";
    foreach (s; a)
        result ~= s;
    return result;
}

mixin (foo ("int ", "x;"));

tError: cannot evaluate foo(cast(invariant(char)[][])((invariant(char)[][2u]
__arrayArg244 = void;
) , (__arrayArg244[0u]) = "int " , (__arrayArg244[1u]) = "x;" , __arrayArg244))
at compile time
attribute argument to mixin must be a string, not
(foo(cast(invariant(char)[][])
((invariant(char)[][2u] __arrayArg244 = void;
) , (__arrayArg244[0u]) = "int " , (__arrayArg244[1u]) = "x;" ,
__arrayArg244)))
