I share your opinion about reinventing, and reuse of existing code. And that was, why I did look at several Template Modules, including the Template-Toolkit. The latter looked for my problem as if shooting at sparrows with canons (literal translation of a german saying).
I preferred the 30 line solution over the installation of a new, some hundred kByte Moduleset at the customer's site. All constraints are known from our former OS/2 Rexx implementation.

... and at least it is not meant as a CPAN module, just a code-snippet. (Should I have posted it in discussions?)

Nevertheless, I did not know your article before, it is a good example. Other projects require different solutions.
