>That said, C# solves this problem near perfectly.
Hadn't it already been solved in Java even better before? It doesn't look right to praise C# for resolving the problem when C# merely took that idea from Java. C# came up with the templates part though.
What C# didn't copy was the idea of turning every source file into a binary file. A library is just a zip archive of those .class binary files. What's the advantage for C# to not have .class files and to pack everything into a 'proprietary' library format? Why haven't they copied the zip-idea, too?
