Re^2: Use of $AUTOLOAD and strict

That's wrong. The ones that have to be declared are the ones not in perlvar. For example, $^W does not have to be declared, but perl -e "$,=$\=$/; print keys %::" does not print it.

Update: the exact rule is in perlvar:

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. A few other names are also exempt in these ways: ENV STDIN INC STDOUT ARGV STDERR ARGVOUT _ SIG

The docs you quoted support me. `perlvar` and some variables outsides of `perlvar` don't need to be declared. My snippet lists all the variables in `perlvar` AND the variables not listed in `perlvar` that it acknowledges. I did mean to mention the non-text variables from `perlvar` (e.g. $^W) don't need to be declared either.	[reply] [d/l] [select]

Note that both of these still leave out `$a` and `$b`, which are subject to the package statement yet do not need to be declared via `use vars` to be used inside a `use strict` environment. `-- @/=map{[/./g]}qw/.h_nJ Xapou cets krht ele_ r_ra/; map{y/X_/\n /;print}map{pop@$_}@/for@/` [download]	[reply] [d/l] [select]
