I still don't understand why we need to have a unit at all (I see nothing in
the algorithm that depends on actual units). Could it not be unit-less, and
work just as it is? It would be confusing (IMO) to force the usage of m/s for
some vectors, and then let people use whatever they want (e.g. inches or miles)
for other vectors.
I'd personally prefer an all-or-nothing solution: either all vectors are in m
and m/s, or they are all in [custom] and [custom]/s, or possibly even
[custom_length] and [custom_length]/[custom_time] (like miles/h).
