Treats ARRAY as a stack by appending the values of LIST to the end of ARRAY. The length of ARRAY increases by the length of LIST. Has the same effect as
for my $value (LIST) {
$ARRAY[++$#ARRAY] = $value;
}
but is more efficient. Returns the number of elements in the array following the completed push
.
Starting with Perl 5.14, an experimental feature allowed push
to take a scalar expression. This experiment has been deemed unsuccessful, and was removed as of Perl 5.24.
