Erlang absolutely does have this 'in common', and it makes this faculty known every time you start up the Erlang REPL.

In fact, I think there's a case to be made that it may have the most refined implementation for scheduling M:N processes (along with more advanced thread affinity, alternative RQ dispatching, SMP awareness, etc).

Was referring to the fact they're all languages which compile to native executables.

Well you’re either confused or being purposefully ingenuous. The original poster, samuell, said nothing about languages which compile to native executables, he said he’s looking for “languages with light-weight threads automatically mapped (multiplexed) to physical threads, like in Go”. Hence the suggestion of Erlang, which is valid. Further, making a generic statement that Erlang is “slow af” adds nothing to the discussion.
