Physical units in Julia

[tfiers]

@ChrisRackauckas

The problem is that putting units in the type domain is basically antithetical to having different units in an array type. Unless you have at most 4 units, then you would need a separate way of doing it since otherwise you’d be beyond union splitting

I do not understand this (due to limited julia internals knowledge). Is this about arrays containing different units, like [8 GHz, 8 mm, 8 kg]?
