I doubt it gets used very much, but as long as Matlab has it, we could

first used.  A prototype example is isdir.m in that directory.

OK, I'll do that. It should be easy to also do it for anonymous functions: just check for function handle with class(), determine whether it is an anonymous function and get the text of the function body with functions(). Then apply the same transformation as we use for inline functions to that string, then return a new function handle constructed from that string.
