Please, do.

True, it is a common rite of passage. True, there are dozens available on CPAN, true, you should study those. Odds are you're not going to beat something like Text::Template

But false, writing your own is not a waste of time. It's a great way to focus on the issues involved in what a template system should do and on what you really want it to do.

I don't think there is any substitute for learning by doing. Studying the derivation of Fermi's Golden Rule #2* is, speaking from direct experience, far less enlightening than closing the book and deriving it starting from a blank sheet of paper.

All, IMHO, of course.

* Roughly, Fermi's Golden Rule #2 is a general expression for the transition rate of a quantum system, per unit time, from some initial state to some final state, where the situation is complicated enough to require being modeled as a perturbation of some more simple situation. Got all that? Pop quiz tomorrow. :)
