Time for sets2 and dict2 :). We've already got pg2, phash2, rebar3...
Putting numbers at the end of functions/modules/programs seems to be a
pattern in Erlang.

I'd definitely want it deprecated and removed eventually if it were
determined the memory size tradeoff is worth it for the speed

Personally I'd prefer to just get a map when my current code upgraded
OTP versions, but understand that especially since sets and dicts aren't
types, so binary_to_term can't do the conversion (aside from checking
the structure of the tuple it decodes but that is scary), this is asking
for trouble.
