Concurrency or not concurrency?

[NobbZ]

There is that rule in the README:

• single-thread is preferred but you can add multi-threaded or multicore versions too

This reads as if there shall be a singlethreaded contribution for a language, and then multithreaded contributions can be added as seperate entries.

Now there was this cleanup which threw out quite a lot of programs in languages that had multiple entries.

Since Elixir is a language that bets on concurrency, I'd like to retry a concurrent version before starting this in Erlang.

So how do we handle this?

It would be very easy to add a CLI-switch/subcommand to the script which does enable/disable concurrency easily, but then still the question remains, how to handle it during the runs?
