Re: Perl oddities

Perl doesn't DWIM in:

    sub add ($$) {$_[0] + $_[1]}
    my @arr = (3, 4);
    print add(@arry);
[download]

It issues a warning and prints 2, not the 7 I'd expect.

Perl doesn't DWIM in:

    sleep 2.5;
[download]

You can tie some magical variables, and get the expected effects, but with other magical variables, no subroutines tied to them are ever called.

$ perl -wle 'print+(localtime())[5]'
105
[download]

C all over again.

brian, are you going to collect the results here, and give them to Larry before Perl6 comes out? ;-)
