Hello

I am discussing on module-authors@perl.org about a module I would like to put on CPAN.

A proposal was made to improve the interface of the module; the suggested patch was to add a piece of code like this:

$date = ref $date eq 'ARRAY' ? $date : [ split(/\D+/, $date) ];

But another one said:

Never use the value of ref() except in a true/false test.

The correct way to tell if something is an array ref is

    ref $date && UNIVERSAL::isa($date, 'ARRAY')

Do you agree? And why?

Ciao!

The very nature of Perl to be like natural language--inconsistant and full of dwim and special cases--makes it impossible to know it all without simply memorizing the documentation (which is not complete or totally correct anyway).
