I have the parameters as Variant[] params and a function/delegate

Normally I'd push the parameters on the stack and

A can be strings or char, how can I easily deal with both? (e.g.,
a.length = 1 for a being a char... and also a[0] = a, so to speak).
That is, I

Even full inlining can't and won't do anything about template

Hi.
Is it possible to write something like that?
void error(Args...)(string msg, Args args, string file =

?
Currently not, but how could it be done? I wont like to write:
error(format(msg, args));
Thanks in advance. :)

its constraints, its invariants, your needs, and
