It's important to know that those "constants" aren't as efficient as their
non-method syntax cousins:

  package FOO;
  use constant BAR => 10;

  package main;
  print FOO::BAR;  # at compile-time, Perl makes that 'print 10'
  print FOO->BAR;  # FOO->BAR doesn't become 10 until run-time

So you're not saving anything.  In fact, I bet THAT is SLOWER than
$FOO::BAR.  *AND* it won't interpolate (easily) in strings.  All the more
reasons to use real scalars.
