Well interestingly enough, li ls and lst don't appear in the non-Scheme source of Arc, except for lst in the borrowed mergesort.

What about xs and ys, do we get the hounds too?

Looks like my code when it's a three-liner and it really is a bit much to be coding (in my Algebra program):

  (loop for denominator in denominators...
You are right (guessing at the implicit): "list" is a terrible name for a variable unless someone really is writing a general purpose list manipulation function, but we do see "lst" quite a bit over on c.l.lisp.

btw, the real question is whether you see "list" as a variable name in the Scheme source.

xs, ys, as, bs set off my Haskell alarm. They're pretty obvious and general, but something about pattern matching makes them unavoidable:

   interleve [] _ = []
   interleve _ [] = []
   interleve (x:xs) (y:ys) = x:y:(interleve xs ys)
