Are users more tolerant of a slow programming language if it has good multithreading or green threads? I'd be willing to use a PL with good ergonomics that runs at 0.5x speed if it's easy to saturate multiple threads. (PLs focusing on single-threaded performance are common!)

Suppose you want to make a small, hackable interpreter, so you write an AST walker. Could you recover performance by supporting lightweight threads that use all the CPUs? The Python GIL preferred single threaded performance over multithreading, this is the opposite.

TIL that you can give your threads names!
