These would both be errors that the compiler could and should check
for, if declaration checking is enabled. However, they would not be
syntax errors.

Sure, why not.

In that case the other module gets compiled when the IMPORT_NAME
instruction is executed. That says that compile time and runtime are
really the same thing in the current system.

Yeah, maybe some optimization is possible.
