RPython is not the language you are looking for.
No urllib, no xml, no codecs... open() is not even supported!
If you want a statically typed language, write C or Java.

But Python has strong type checks, only at runtime.
I think you'd better write unit tests, or some scripts to exercise the
various tools.
Good code coverage will catch all typos and also many mistakes a compiler
wouldn't tell you.
