Function argument for setMatchlist?

[lukehorvat]

It would be nice if one could specify a blacklist/whitelist function as the first argument to setMatchlist, instead of (or in addition to) an array of regular expressions. For a project I'm currently working on, I need to do a few things programmatically to determine whether a URL should be cache-busted; it's not quite as simple as checking whether it matches a regular expression.

The function would take config.url as an argument and return a boolean indicating whether it is a "match" or not.

What do you think?

Which method signature would you prefer?

setMatchlist(function, boolean) // Only function can be specified.

or

setMatchlist(functionOrRegexArray, boolean) // Function or array can be specified.

Personally I prefer the former (since it's pretty easy to write a function that matches on regular expressions), but it would break backwards compatibility.

Let's not break backwards compatibility.
What about a third alternative, adding a new method:

setMatchFunction(function, boolean)

and leaving setMatchList as it is. If matchFunction is set, it is used, otherwise it falls back to matchList
