Python's "only one way to do it" philosophy isn't good?

I didn't -- been there, hated that.  Each project group ended up
defining (formally or informally) the subset of PL/I it was using -- and
when one had to work with multiple groups, it became yet one more
nightmare to recall which features were in the subset of which group(s).

If there are just 30 "operations", for each of which the language offers
two ways to perform it, that one language becomes over a billion
languages when "subsetted" by picking just one choice for each of the
operations.  Absolutely crazy -- total and utter waste of effort on the
part of every programmer, every group, every compiler author.

PL/1 is basically gone, but its legacy of "take what you need and leave
the rest" is unfortunately alive in other languages that are blind to
the enormous advantages of simplicity and uniformity.
