I'd say the majority of my code does not involve a large variety of types
within a certain bit of functionality -- so unit testing this is pretty
easy. Even in a case where a piece of code could be working with an object
of one of many different types, I'd think many cases could still unit test
each combination. And in cases where I need to verify the type I'm working
with, I can still code this in Ruby.

To me the flexibility and freedom from not having to type everything (plus
type in all the overhead typing code :) is well worth the trade off for
type-safety - especially with unit tests continually exercising the code.
