I've heard that in some other
languages, if you call foo(3), and foo() changes the value of it's
argument to 2, then subsequent calls to bar(3) will pass a value of 2 to
bar(). That sounds like such a ridiculous mis-feature that I hesitate to
identify which languages I had heard accused of having that feature ...

I heard that, too. I think it was on some early FORTRAN compilers, on
early machine architectures, without stacks or reentrancy. And with the
weird FORTRAN argument-passing conventions.
