SYNOPSIS

package foo;
use Meta::Ds::Stack qw();
my($stack)=Meta::Ds::Stack->new();
$stack->push("mark");
my($poped)=$stack->pop();

DESCRIPTION

This is a library to let you create a stack like data structure. The internal representation is that of an array. Why should you want this ? Well - its not very nice to write $#$stack when you want the size of the stack... This is mainly a OO wraper for a stack...

FUNCTIONS

new($)
top($)
push($$)
push_set($$)
pop($)
size($)
empty($)
notempty($)
print($$)
