Sorry. Generally, when I hear people complain about the lack of "types" in a dynamic language, I'm pretty sure what they mean is [static] "classes", so that "intellisense" (auto-complete, for non-MS/VS-bubble-land) works.

Then next, a hair-brained XML configuration scheme (with reflection) will be used to work around the inevitable deficiencies, which an IDE plug-in may or may not parse accurately.

Tragedy ensues. (Or hilarity, if I get to stand back while somebody else has to support the monster)

YMMV.
