I already provided an answer to this in my previous post.

Another consideration is that in order for all this to be more compact, easy and
elegant, it must be possible to write (in XPath!) expressions like this:

func(someFunc, someOtherFunc, $sequence)

or 

(func(someArguments)) (otherArguments)

In the first case functions are passed as parameters to func().
In the second case, func() returns a function, which is then applied on
otherArguments.
