Perl 5 version 26.2 documentation
- push ARRAY,LIST
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
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.
