Point-free programming style

How do I write the factorial function in point-free?

fact n = foldr1 (*) [1..n]

Which is faster
add1 = 1 +
or
add1 x = 1 + x
???

Its just way more convenient to write in javascript(tracemonkey is near C++ speed in some case).
I'll try High-level Assembly or Linoleum assembler sometime.
