in reply to Why did @$ variable bite me in the ass?

IIRC do global symbols (aka type globs) of special vars in perlvar reserve all types.

And $$ exists.

Same with @a or %_ and so on ...

We had this discussion already many times, try super search for more details. :)

HTH!

    Thank you for the speedy reply! I am reading Chapter 10 of Programming Perl, 3rd Edition, looking for the global symbol bit of wisdom you refer to.

    I did use the Super Search before posting, but my query for "@$" did not produce anything related to my issue. What search terms did you use?

      I queried old biological device, glued to my neck and fueled with with sandwiches and coffee, but unfortunately not linkable. ;)

      I'll try finding it (slow with mobile) and will update/msg you. :)

      update

      Sorry, can't find it, but I'm sure we had this discussion... but people always complain about various vars, not only $$.

    Perhaps someone will make a list of all of the variable names that don't trigger strict messages?

      Isn't it pretty obvious?

      Parse perlvar or English and all missing sigils per listed symbol don't bother strict.

      Eg symbol _ => %_ is ignored, cause $_,@_ exist.

      edit

      And to be sure try string eval with strict and catch (the missing) error.

      update

      Hmm parsing %main:: might do already ... Can't check while mobile. (update: Nope! :)

        So there's quite a lot of interesting stuff in there.
