That would be a massive breaking change.
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.
Yah, that would work (note we are not talking about breakage; perhaps
you meant no language addition?). That would (a) miss the dependency
carrying aspect and (b) would be suboptimal. The moment any unqualified
symbol is looked up in a module, all modules it imports need to be
loaded. This could be avoided by using consistently fully qualified symbols.
The comment about alternatives in the DIP does mention that but without
going into details. Let me know if you think they should be added.
