Kind of. When you say sub foo {my $bar}, perl doesn't actually allocate a new variable every time you execute foo. Instead, it just clears the value. When you say state $bar it doesn't do that either. (This gets into the variable/value split, which is generally not talked about much in perl5-land. Suffice it to say, I did mean to say "variable" and "value" when I did.)
