Re: shift vs @_

in reply to shift vs @_

To put it one way, they are always using @_. If you don't give an array to shift, it uses @_.

I think the "shift" idiom caught on out of laziness, though it's not as slick with more than one argument. You can write:

my $var1 = shift;
my $var2 = shift;...

Likewise, you can write:

my ($var)=@_;

for only one argument.
