Walter Bright: Thank you for your answer.
> The error is not a mismatched file name, which is perfectly legitimate in D. Do you mean that in D it is OK to have a file named "foo.d" with inside it at the top written "module bar;" ? What's the rationale behind this? (I don't like this). >The error is two different files have the same module name.< Maybe I am missing something, but: - there is a module "bar" in the file named "foo.d" - and there is the module "test" in the file named "spam.d". All four names are distinct, there are no name duplication (and the imports can't change this basic fact). Bye, bearophile
