Well, HOM removes that requirement. It's just

  [[array do] doSomething];

...

The implementation concept is pretty easy, the object returned by "do"
catches the "doSomething" invocation and executes it on the source
object.

The major problem I have with this approach is, that it requires a
working NSInvocation, which is difficult to have on all platforms ...

You can also have as much parameters as you like in HOM.
