It looks like this discussion has terminated, and I think I've made whatever points I wanted to be made so I'll leave it at that. But since this seemed to be unclear, let me recapitulate:
BEAM docs are not needed to produce a second source implementation, as shown by several examples. (1)
Also, there has so far been little practical interest shown by Erlang users in such a second source. So implementation efforts may be in vain. (3)
My personal view, at least, is that most of the difficulty in "keeping up with The Real Thing", Erlang/OTP, would be not in reproducing BEAM but in writing a fully compatible implementation tracking the rest of the runtime, ERTS. (2)
So, is there a _practical_ case for doing these docs? In particular, will the effort result in useful external contributions that outweigh time spent? Not at all clear to me.
Hope it helps.
