No.  I understand that formal proof systems, as well as automated
theorem provers, have been difficult to develop.  When I took ML, the
homeworks were to prove the correctness of an interpretation of a
program, and the unique existence of a meaning by induction.

But I, and I imagine I'm not the only one, would love to know the
example that C# developed faster than Python.  I suppose the fact that
the line of wx specification that has two identifiers where C# has one
is more of a drain on programmer resources than may commonly be
recognized--- not the same as the cost of one extra word in a paper or
in an editorial.  Similarly, maybe the program that has one extra
identifier in a line takes a lot more time to develop.  Perhaps it's
the "7 +/- 1" trend in attention span that makes the difference large
in that case.  8 identifiers would in that theory be a big deal, so
the example in C# could make the case for it.
