I went to a talk by Stepanov about the Standard Template
Library in C++.  One of his examples was a geneic GCD
algorithm which works on integers and polynomials.  Thus,
stricter typing and generic programming don't have to
be the same thing.

In Python, this could be done by a syntax requiring not
that "i" and "j" are ints, but that type(i) == type(j).
