Fix code review comments.

Added aliases for inferred() and assign_type(), refactor some uses of
ternary if, remove some now-unused internal functions in rebuilder,
replaced the mutating docstring function with one that returns values
as well as side-effects, change back to lazy-object-proxy, and add keyword
args to the Module call in rebuilder.
