Thanks. Does the second sample pre-compile the regexes?

    I believe that we're mixing terminology here, as "pre-compile" isn't exactly what you're wanting to ask. Yes, the code is only compiled once and after that point it will not need to be recompiled.

    I've used this type of mechanism to program configurable filters. Letting a user edit a config file where they specify anonymous subs like that which are later eval'd and used in my larger package.
