Many of our runtime type failures are due to reified dynamics - e.g., allocated objects with type Foo or (dynamic)->dynamic.

We can do a few things to help users address these where problematic:

A info / warning when such a type is concretely allocated.
Embedding metadata to tie these objects, at runtime, back to allocation site (for easy debugging).

vsmenon added the static checking label
