"when we see people using "lst" in code they mention on comp.lang.lisp, we unleash the hounds who chase them over the fence to comp.lang.scheme where they belong" : be careful, it's not necessarily a schemer, it might also be pg, writing a function where both l and ls are already bound...

Excellent point, it might just be an Arc welder trying to save a char -- well, we checked with the hounds and they say a CL-style defmacro and (is nil #f) -> t don't mask the Lisp-1 scent, but they loved On Lisp and Ansi Common Lisp and ViaWeb being done in CL so pg is welcome any time.

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)
