It's not built into the language? How can we be sure this project with 2k Github stars won't segfault, memleak, deadlock, or have some other horrible bug [1]? I haven't done full due diligence, but I'm already suspicious. The open tickets don't look good [2].

In any case, this should be a language feature.
