I also like this convention in Scheme, but I don't like the way it looks
in an infix-laden language like Python.
Whereas:
(predicate? arg1 arg2 ... argn)
... looks good and legible to me, I find:
predicate?(arg1, arg2, ..., argn)
... far less appealing, because of the juxtaposition of ?(.
I realize this is purely a personal aesthetic distaste, but Python is
generally quite a pretty language, and I'm afraid this addition, as
sensible as it is, might work against that for comparatively little
benefit.
