So is there going to be a way to specify at the function (or template) 
definition site that the function (or template) produces a compile-time 
string which is to be mixed into the call site. eg:

// The 'mixin' specifies that the result should be mixed into the call site.
mixin char[] writefln(/*params*/)
{
     ... // Generate code
     return generatedCode;
}


Sounds good.
