Re^2: how do you check if it's compiled away?

darn, i forgot about that. i had originally had a `uc` i was trying to optimize away. so the working version is:

use constant DEBUG => do {
    (my $p = uc __PACKAGE__ ) =~ tr/:/_/s;
    $ENV{ $p . '_DEBUG' } || 0;
};

And all for nothing, because I believe in most (I dare not say "all") systems, environment variables (and `%ENV`) are case insensitive. Well, it definitely doesn't hurt.	[reply] [d/l]

POSIX requires that environment variable names be case sensitive.	[reply]

Environment vars are definately case sensitive on Debian, and there's no special treatment of `%ENV` by perl: `print "uc => ", $ENV{EDITOR} \|\| '', "\n"; print "lc => ", $ENV{editor} \|\| '', "\n"; __END__ UC => emacs lc =>` [download]	[reply] [d/l] [select]
