Wouldn't static type-inferencing of Python give the same benefits, without forcing programmers to write "Java-like" declarations? Type inferencing would catch potential uninitialized variables, calling non-existent methods, etc. ... and combined with a tool like lib2to3 could be used to automatically insert type annotations into the code.
