Yes, I am.  If you have a need for using count() or index() on tuples,
you're using them the wrong way.  Tuples should be used in situations
where a small record (in Pascal terms) or struct (in C terms) would be
used in other languages -- not as immutable arrays.

String methods were introduced for a good reason -- the introduction
of Unicode.

I think adding these particular methods to tuples will just propagate
the misunderstanding that tuples are primarily sequences -- they're
not.

I didn't mean code size -- I meant stuff that has to be taught,
learned, documented.

Thanks for PySol, Markus!  It's an excellent game and has even drawn
people into learning Python!
