Question:
If I have an array and want to take the first element off and return it, I
would do it like this:
return (@myArray) ? shift(@myArray) : undef;
How would I do similarly with a hash? I have something like this:
return (exists $myHash{$val1} ) ? $Hash{$val2} : undef;
But these leaves the value in the hash. I know I can save the value first,
then DELETE it, and then return it. But I'd like to do it all in one step.
TIA
-Jeff
