in reply to Use of a global scalar
This is a fine moment for
perl -le'print map{pack c,($-++?1:13)+ord}split//,ESEL'
;-)
See our. Variables declared with our aren't global.
The only global variables in perl are the 'special' variables, e.g. $_. But with these, "global" means only that the symbol is available everywhere, without any previous declaration - but the actual value accessible through that symbol is subject to localizing and aliasing.
The documentation for our stresses within the current scope - and a block boundary is a scoping boundary.
Say use vars qw($text) to have a package global, or use ${^_text} to have a really real global (the symbol is bound to the package main, though).
--shmem
_($_=" "x(1<<5)."?\n".q·/)Oo. G°\ / /\_¯/(q / ---------------------------- \__(m.====·.(_("always off the crowd"))."· ");sub _{s./.($e="'Itrs `mnsgdq Gdbj O`qkdq")=~y/"-y/#-z/;$e.e && print}
