SDC do parse the module only when an identifier resolution reach 
top level, and then populate the module's top level symbol table 
without running any semantic analysis on any of its symbols.

Symbol are analyzed on demand when they are used. I think this 
achieve something close enough to what Andrei was proposing and 
is not breaking.
