in "static code" you can use "42.stringof" but, IIRC, that won't work in 
other CTFE functions.

 Reply to d-bugmail puremagic.com,

Example:

template foo(int line = __LINE__)
{
  pragma(msg, line.stringof); // prints 'line'.
  pragma(msg, toString(line)); // should print a number of some kind. Currently
does not.
}

That is pretty much why I need this.

You could try

    import std.metastrings;

    pragma(msg, ToString!(42));
