Re^3: Syntax Question Related to "join" on a Complex Data Structure

Hi perldigious,

tybalt89's suggestion appears to be Postfix Reference Slicing, which is part of the new Postfix Dereference Syntax, which says:

In Perl 5.20 and 5.22, this syntax must be enabled with use feature 'postderef'. As of Perl 5.24, no feature declarations are required to make it available.

Hope this helps,
-- Hauke D

That does help, thanks haukex. That `use feature 'postderef';` reduced the `warning` to: `Postfix dereference is experimental at Web_Chat_IP_Match.pl line 142.` So "sufficiently modern" really meant "the most recent version" then. :-) I'll probably stick to the old block notation anyway, at least for the near foreseeable future. I'm just more comfortable with it I guess. I love it when things get difficult; after all, difficult pays the mortgage. - Dr. Keith Whites I hate it when things get difficult, so I'll just sell my house and rent cheap instead. - perldigious	[reply] [d/l] [select]

Hi perldigious, Oh, right, forgot about that. You can disable the warnings yourself, or there's experimental: `use feature 'postderef'; no warnings 'experimental::postderef'; # - OR - use experimental 'postderef';` [download] Regards, -- Hauke D	[reply] [d/l]
