Like Ovid said: 

my %stacks = ( A => [],
               B => [],
                  .
                  .
                  .
               Z => [],
             );

# microseconds later...

my $current_stack = $stacks{ K };  # for example

push @$current_stack, 'whatever';

# etc.;

As long as you deal with references (like $current_stack) above, the changes you make will be reflected in the stacks stored in %stacks.

You can initialize the stacks more succinctly with something like this: 

my %stacks; @stacks{ @names } = map [], @names;

[download]
...where @names holds the names of the stacks.
