I don't need to return a constant

You miss the point entirely. (I beginning to wonder if it is deliberate.)

If you return anything that is not an lvalue, it is a constant. The very definition of rvalue, is "unassignable". Perl won't let you do that.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority". The enemy of (IT) success is complexity.
In the absence of evidence, opinion is indistinguishable from prejudice. Suck that fhit
