Guido van Rossum On Strong vs. Weak Typing

Bill Venners writes "In this interview, Java creator James Gosling says, 'There's a folk theorem out there that systems with very loose typing are very easy to build prototypes with. That may be true. But the leap from a prototype built that way to a real industrial strength system is pretty vast.' In this interview, Python creator Guido van Rossum responds with 'That attitude sounds like the classic thing I've always heard from strong-typing proponents. The one thing that troubles me is that all the focus is on the strong typing, as if once your program is type correct, it has no bugs left. Strong typing catches many bugs, but it also makes you focus too much on getting the types right and not enough on getting the rest of the program correct.'"
