I guess that most of these were made for the sake of argument rather than out of concrete need. Actually, static-only dimension checks have almost no use for engineering. Scientific computations might be different, however require more than just dimensioned scalars, e.g. dimensioned vectors, matrices etc. I think they just choose a units system and don't care about dimension analysis. -- Regards, Dmitry A.
