The dynamism of ruby does make things difficult, if not impossible, to fully realize until runtime. Incidentally, tests are popular in ruby, and give us runtime examples to work with for stronger analysis. If we're just spitballing, as big as TDD is in rubyland, I'd love to see tests themselves become first class documentation, built with the rest of the class docs as yet another form of annotation.
