Admittedly, I haven't looked at this module (or really tied things in general recently), but isn't there always an additional speed hit for using a tied variable?

Yes. And 'use strict' and 'use warnings' also impose penalties -- you have to look at the situation, and see if the penalties from using something are worth its benefits.

Sometimes, it's worth using something in development, and then take it out before it goes into production. Eg, in the examples from the original poster, only constants were used to access the hash, so FixedKeys isn't needed after the program's been written and tested. (if you were using potentially tainted variables as hash keys, you might want to leave it in, but you'd have to look at the costs, benefits and other risk factors for that particular case).
