What you describe is easily done with Getopt::Declare. I haven't had the multiple module situation, so I haven't had to use an "accept parameter" function, but that could easily be done.

The parameter description is just a string passed to G::D. The string can be built up piecemeal by modules as they load (or perhaps each module adds a key to a hash, and after all modules are loaded, the hash is processed into a string).

The code callbacks are called "actions" in the G::D documentation. Parameter checking syntax, either by fundamental type (e.g., integer), regex, or code block, is already provided.

Perhaps I should develop a helper module for G::D to do what you suggest?
