Re^5: How to conditionally execute a subroutine defined as hash valueby BrowserUk (Patriarch)

Not sure i like the lock-in you get with the anon sub approach.
Personally, I see your method causing more lock-in than mine. You're committing them to a single parameter.
Of course, you can then make it an anonymous array, and pass that.
But now you are creating yet another level of indirection and nesting, and parallel data structures, all of which then needs to be mentally unwound to work out what gets passed to what.
The delegate -- anonymous sub that encapsulates code references along with their arguments (by closure) -- is a very well tried and tested mechanism used by FP languages almost exclusively. It's clear, concise and can usually be in-lined.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

In the absence of evidence, opinion is indistinguishable from prejudice.
