Can anyone explain to me why the scalar $ENV doesn't show up in a package with its "fully-qualified" package name?
% cat xxx.pl package script; $env = 1; $ENV = 2; print "\$env = '$env'\n"; print "\$ENV = '$ENV'\n"; print "\$script::env = '$script::env'\n"; print "\$script::ENV = '$script::ENV'\n"; % perl xxx.pl $env = '1' $ENV = '2' $script::env = '1' $script::ENV = '' %
I suppose this has something to do with the special status of %ENV, but that sure seems to run counter to the usual distinction between a same-named scalar and hash.

This behavior is consistent on Perl 5.00345 and 5.6.0, so it's not a version-specific bug, at least...

  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
