hmm.  I'm not so sure about that...

with Greg's scheme, SRE needs to create a list full of buffer objects, =
while
the SliceList scheme involves creating *one* object per substitution -- =
and
to create that object, SRE only needs to copy slots from the match and
substitution objects, and bump the reference counts.

(...and btw, using raw buffer objects to point into a set of strings of =
mixed
types doesn't sound right to me...)

I think I'll stick to the SliceList model, with or without explicit =
support in
the string join methods.
