Re^2: Search List

Aside from note by Roy Johnson, I would change

if ( $searchlist{$_} ) {print "Match Found"}

if ( exists $searchlist{$_} ) {print "Match Found"}

~~since your test would add a entry to the hash on each word which isn't there.~~
Update: This is wrong, see reply.

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. holli, /regexed monk/	[reply] [d/l]

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]
