...if the word on the left starts with a number and consists only of numbers.
As long as you don't want to keep any leading zeros.

    As long as you don't want to keep any leading zeros.

    The claim is less accurate than even that:

    % say "010 => 11" 8 11

    Also:

    % say "123456789012345678901234567890 => 30" 1.23456789012346e+029 30 % say "'123456789012345678901234567890' => 30" 123456789012345678901234567890 30

    But I've also long considered the failure of "use strict; Foo::Bar =>" to likely just be an oversight. I suspect a patch to Perl's tokenizer/parser to allow '::' in so-called barewords would not be terribly difficult and might even be accepted by p5p.
