Fair enough.

Okay, what's your view?  Mine is that du'u and ka mean the same
thing, except for their x2 place, and for the default number of
ce'us (0 for du'u, 1 for ka).

An expression of the function is not the name of a function.
So "le ve fancu fo la faktorial." (left out fo last time)
means "the program, or whatever, that expresses the factorial function."
This is a Good Thing.

MEX is the obvious way of expressing a program (mathematical
expression).  With the article "li" it refers to the value of the
program; with the article "me'o", which is wanted here, it refers
to the text of the program.

We just don't have anything defined for "\x.".
