Hm, what's the shortest way to do this: I have a hash where one, and only
one, key begins with a number, I don't know its value and want to assign
this value to a variable.
If I were to do a foreach loop, I'd do this (presuming that %hash is
already defined):
foreach my $key(keys %hash) {
if ($key =~ /^\d/) {push (@keys, $key); }
}
But since I know there will only be one key where this condition is true,
looping and creating an array seems like a waste.
