...and then import them all again, even when they're in the same file, which I think is one of the most bizarre aspects of the ELF mechanism - I can certainly see that it allows the extra flexibility of overriding functions, but I've never thought "I'd like to be able to easily replace any function in my application with one from a library". I don't imagine it's a common use case, since on Windows it would be the equivalent of having a PE import itself (is this even possible?)
