Of course, you're right, puristically speaking.
If I only put calls to module "Out" in my IF const THEN END, then the code that is optimized out does not change the logic of my code.
This is what I meant by "not really different": not binary the same, but logically the same.

For the special case of debugging output, your proposed
    IMPORT Out := OutStub;
would be indeed an alternative. With this, your productive binary still includes all the debug code and strings.
