See "perldoc perlfunc". It has a section "Perl Functions by Category".
Does any of the functions listed for arrays or lists sound like it might do
what you are looking for?
Maybe a similar name as a popular Unix command (hint, hint)?

For details see "perldoc -f grep".

this may help if you mean 'undefined' array elements by 'empty'
@out = grep {defined} @in;

this may help if you mean 'undefined' array elements by 'empty'
@out = grep {defined} @in;

And this may help if you meant "empty" when you said "empty":

@out = grep length, @in;
