Well, that actually needs to be transparent to be useful for the way I want to use it. I can't even understand why would one need sub-modules so far. The actual reason is to have different members (i.e. every method) or sets of members of a same class to be implemented in separate files. I just hate to have long code files and to have code above and below a function declaration. Partial classes in C# are an example of how can that be implemented the way I like it. The only problem with the C# way is it adds an additional indentation level. I would prefer the module (or even the class) to be declared in the beginning of the file without contributing to indentation.
