but for testing if a hash contains an element, I normally use
"exists":
Your wording "if a hash contains an element" is ambigous IMO. A hash
or associative array consists of key/value pairs, where the keys are
indexes and the values are considered to be the elements (I think).
if (exists ($hash{'mykey'})) {
print 'mykey exists.';
}
That's fine, as long as you are aware that $hash{mykey} may well be
undefined even if it "exists".
