Re: Constant names come into conflict with Perl style?

There is nothing that says that your constant subs have to have all upper case names.

My personal preference has evolved to be mixed case names starting with an upper case letter. This avoids the conflict you describe, and (in my schema), distinguishes constant subs from other subs which are mixed case but start with a lower case letter.

I also find it infinitely preferable to so called Readonly variables--which is just a nonsense IMO. (Ie. variables that don't). Constant subs also allow Perl to perform optimisations that are not possible with 'Readonly variables'; and they don't carry that modules overheads.

"There is nothing that says that your constant subs have to have all upper case names."

That's true, there's nothing that says it, but if you grep your /usr/lib/perl5 for 'use constant', you will see that the overwhelming majority of constant names are upper-case.
