If you have a scenario where you have lots of these arrays floating around and you'd rather not go and change them all to use $array[0], $array[1], you could just put in your code a new function: sub mkdir {CORE::mkdir $_[0],$_[1]} which would then split it up for you.

I'm pretty sure I've read a few times how prototypes are evil, but I think this is even more evil than normal prototypes: with normal prototypes, I can fake my way around them with the & sigil. Not so with built-ins.

(...) No, that doesn't work, either. You have to do both: create the function, AND call it with &. Doesn't work: 

$ perl -e '@x=qw(foo 18);sub mkdir{CORE::mkdir($_[0],$_[1])};mkdir(@x)
+';ls
2

Works: 
$ perl -e '@x=qw(foo 18);sub mkdir{CORE::mkdir($_[0],$_[1])};&mkdir(@x
+)';ls
foo

Also does not work: 
$ perl -e '@x=qw(foo 18);&mkdir(@x)';ls
Undefined subroutine &main::mkdir called at -e line 1.

*sigh* At that point, you may as well call it "MKdir" so it has a different name, and change all your function calls. That's kind of annoying... it's like super-powered evil prototypes.
