You're right and I learn something new all the time.
Building on this though, if you made the constants module, couldn't you
make them subs? I believe this is even how the use constant pragma
functions. Heck make it an object oriented module with static methods
and it's even designed well.

I haven't tested it, but I'm quite sure:
my $p = 'Long::Package::Name';

works as expected. If memory serves this is even allowed under the
strict pragma. If not though, you could always localize a block with
no strict 'refs' where you need it.

I'm not sure if this is a GOOD idea, but I THINK you can actually get away
with something like this: In your module, insert a shorter package name,
but keep the module in the same place. So:
package Foo::Bar::Constants;
#do stuff here
package MyConst;
$Constant
