in thread Scalar followed by parenthetical...

But isn't %_ immune to strict in the same way and for the same reasons as $_ and @_?

Maybe technically :) but according to the current documentation it shouldn't be, because unlike "$a" and "$b" the hash "%_" isn't used by sort or any perl feature

OTOH, perlvar, which lists $a and $b, also says these types are exempt from strict-vars

so what about %_? Makes sense to me for strict-vars to compain , its not like it requires extra chars like %{_} or ${^SNACKS}

curious http://perl5.git.perl.org/perl.git?a=search&h=HEAD&st=grep&s=%25_, http://perl5.git.perl.org/perl.git/blob?f=t/japh/abigail.t#l483

    See perlvar (for 5.10) when there was a section entitled "Technical Note on the Syntax of Variable Names", which contained the paragraph:

    Perl identifiers that begin with digits, control characters, or punctuation characters are exempt from the effects of the package declaration and are always forced to be in package main; they are also exempt from strict 'vars' errors.

    Seems to have disappeared from later versions.

      It's still there. It was just moved to the top in 5.14.

        ... and the title was changed. Not a problem, except it negated my search.
