Lexical (my) variables cannot be localized, as the error tells you. Use my for that :-P

use strict; my $tt = 3.14159; { my $tt = 3; print "In block, \$tt = $tt\n"; print "In block, \$::tt = $::tt\n"; } print "Outside block, \$tt = $tt\n"; print "Outside block, \$::tt = $::tt\n";
local is for globals. But there's a way to get lexical globs, I wonder whether these can be localized... ;-)
_($_=" "x(1<<5)."?\n".q·/)Oo.  G°\        /
                              /\_¯/(q    /

LanX Everybody quotes it, some people read it, and a few people go by it
[ambrus]: LanX: why would I read it? isn't it a book for managers? I don't want to be a manager.
[ambrus]: I don't quote it either.
[erix]: it's really a software book, albeit about experiences from the 60s-80s. People haven't changed all that much though.
[erix]: a software project book, is probably more exact
[ambrus]: Yes, but I'm not managing software teams either.
[ambrus]: I'm not only not a restaurant manager, but also not a software manager.
[erix]: Peter's principle says it' sonly a matter of time ;)
