If I'm getting this (and I'm not sure that I am) there was a a module/article in the last but one or two TPJ about the perl frontend to somebody's extensive language dictionary/thesaurus (sp?) project.

It was far better than that and, the perl part made it extendable (the linquist researchers who created the original didn't appear to want any help extending their db). If only I could remember a detail ...
