Re^3: Search List

That's wrong. Just looking up a hash key does not autovivfy that key. Consider

my %h = ();

print "found" if $h{somekey};

print %h;
[download]

which prints nothing. The key "somekey" is not autovivied.

Oh my, You're right! I've always thought that `exists()` is a ugly exception to the rule, that `$hash{key}` autovivify ``key'' if it doesn't exist. However, using `exists()` is more explicit and I think I'll still use it in turbo-clean code. Thanks for enlightenment.	[reply] [d/l] [select]
