The case of the disappearing angle units, or "the dangle of the angle"

You could then have some non-standard trig functions such as SIND/ASIND for angles in degrees, etc., as well as functions for converting between angle units (so SIND would be more or less equivalent to D->R SIN, perhaps avoiding any D->R rounding error). If there is an angle mode setting, it would only affect which set of trig functions the keys map to.

How is that different from buying a "normal" calculator and always keeping it in RAD mode? Just ignore the other modes and you'd have what you want, right?

In RPL machines you can easily make new commands, such as SIND, ASIND, etc. which changes mode and then does your operation, etc.
