  To be more precise, not "10 different functions", but 10 overloads
of the same function.

Here, the fact that the function name is the same in all 10 cases is
really important.

Also, this approach is rather an exception than the rule in FXSL. If I
remember well, it is used only for f:apply() and f:curry()

Different overloads are used systematically, on a massive scale, to
present "normal" F & O functions as higher order functions and as
curried functions, that is to present their partial applications on a
subset of arguments as a function.
