Include is only a precompiler directive that copies the original source there and checks if the base rules are still valid (strict, superstrict, include, import only at top of the resulting file).
H&K: That is no cyclic import at least it does not sound from your descripting
What you do is multi import of the same BMX. That shouldn't be a problem, I think the compiler makes sure it is only included once. (different way: lazyness = Blide + Framework Assistant ^^ then you can be sure that only the really needed stuff is linked against that. But I would not use FA until your program is going to be shared, just to prevent stupid missing import errors)
