RE: Variable number of arguments

If the arguments are singleton items then I think defining a single
sequence-valued argument is the best approach (it would have been done that
way for concat() except for 1.0 compatibility).

Another approach which Dimitre has used in FXSL is to define 10 different
functions taking 1 argument, 2 arguments, etc.
