No, not the routine that deals with Arrays !
I see code like the following, everywhere:
my $coolvariable = shift;
Why is a new scalar being assigned to "shift" ?
New to Perl... sorry for the lame question, but couldn't find an answer
anywhere.
shift is a built-in function. It's documented under
perldoc -f shift
It removes and returns the first element from an array. When called (as
in this case) without an explicit array, it defaults to either @ARGV (if
called outside of any sub), or @_ (if called within a sub).
