You could do something like:
if (_arguments.length < 24) {
    // insert your code
} else {
    foreach (i, arg; _arguments) {
       char[] fmt = (i + 1 == _arguments.length) ? "{0}" : "{0}, ";
       Stdout.layout()(&Stdout.sink, [arg], _argptr, fmt);
       _argptr += arg.tsize();
    }
}

The code is actually not mine but a slightly modified copy of the actual 
Tango print function.  What I'd _like_ to have my function look like is 
something like this:

typeof(Stdout) print(...) {
    return Stdout.vaprint(_arguments,_argptr);
}

However, Stdout.vaprint doesn't exist.

You make a good point about the implementation of Stdout.print, though.
