Re^3: Make things a *little* easier

Now that would be something I'd like to see in Perl 6 (and which I have missed in the Perl 5 version of the function on a number of occasions).

Makeshifts last the longest.

You seem to be getting different results than mdillon. That's the problem with relying on undocumented details. If you write a sub starting with `my ($a,$b,$c,$d)=@_;` and then calculate defaults if undef or use the undef value for some special meaning, then leaving off args naturally gives the same results. But if you write `if (scalar(@_) < 4) ...` to do something different, then using undef doesn't give the same effect.	[reply] [d/l] [select]

my ($a,$b,$c,$d)=@_;

naturally

if (scalar(@_) < 4) ...
