One extremely common and important use-case of allowing it is this:
foo(string[] args..., string file = __FILE__, size_t line = __LINE__);
Right now as soon as you introduce variadics you can forget about using
__FILE__/__LINE__ at runtime (unless you resort to some inner-template
tricks, but that only works in some cases methinks, probably not at
runtime).
Well, except that example wouldn't work :)
This would though:
foo(string[] args..., size_t line = __LINE__, string file = __FILE__);
Excellent use case though!
