What's the status of Nim's garbage collector? https://nim-lang.org/docs/gc.html Last time Nim came up on HN someone said they were changing from reference counting to tracing. Also seems like the Nim developers are reluctant to make a choice here? GC is a show-stopper for some developers but an absolute necessity for others.

View on HN

Nim has multiple garbage collectors you can change at compile time. Here's the --gc option from the documentation.

    --gc:refc|v2|markAndSweep|boehm|go|none|regions

I don't know if this is up to date or not. There's an open issue on github to improve the documentation on the garbage collector.

My impression from the article and docs is that Nim offers multiple choices specifically because garbage collection ain't one-size-fits-all.
