Not gonna lie... your snippet made me say "WTF?" Why not just do:

  from string import ascii_letters
  '|'.join( ascii_letters )

(I also like list slicing... but only when necessary.)

Yeah, I realized after posting it. (See edit.) The original code was using non-string objects. I basically come up with this to get the same behavior as str.join(). ;-)

    '|'.join(str(x) for x in y) # or
    '|'.join(map(str, y))

The original use for that code was to build a list of parsing objects to create a single parsing object that was the OR'ing of the basic ones.

Aw, heck, code speaks louder than words:

    intersperseM or $ map chartok whitespace

Oh... wait... sorry... wrong language.
