Anybody?

   Speaking as a Python programmer (not a Python developer),
I would say that Python doesn't generally do implicit
conversions.  The programmer keeps track of the types of the
operands passed to operators and functions, and the
operators and functions do what they can with what they get.

   You have it right that the arithemetic operators work so
as not to lose "comprehensivity":  an operation on a complex
yields a complex OR an operation on a float yields a float,
OR an operation on a long yields a long OR the operation
yields an int.  (Those are Python short-circuiting OR's
there.)
