newRPL: Handling of units

[JoJo1973]

Therefore pure numbers are considered as radiants when combined with angular units?

Sounds reasonable: unfortunately the an adimensional quantity involves a number of compromises when dealing with unit-tagged numbers.

The important thing for the end user is that the implementation is coherent and behaves in a predictable and "common sense" manner.

This doesn't make the radians disappear from the units, but makes it completely transparent, as you can have 1_m*r/s, coming from V=r*w, for example, and you can add 1_m/s, they will be considered consistent. You can also convert to 1_kph and the units will be consistent.
There's other side effects, like adding a plain number is equivalent to adding 1_r, or 1_dB. Another, perhaps less desirable side effect is that unrelated non-dimensional units are convertible among themselves: you can convert 1_r into 1_dB and it's not an error: the units are indeed consistent. Also, you can add r/s to Hz and it's OK, because both are 1/s in the end.

I added 1_tr = 2*pi_r, and redefined 1_rpm = 1_tr/min

This means now rpm can be converted directly into other angular speeds like r/s, or 1/s.
