I can't figure out the point of having both go and spawn. `spawn` seems to be an ordinary thread spawning mechanism, generating a handle that you can join with (but not cancel? can't find that for certain, it's not actually in the tour but is in the SPEC.md). `go` inherits all the problems of go routines. You can't join with it, you can't cancel it, you have to build other infrastructure on top of it to achieve those effects. As neat as golang was 17 years ago when it came out, this was and still is a major weakness of the language which has resulted in the community developing conventions (now standardized in the go standard library and particular usage patterns) around how to deal with it. I don't get why you'd half fix it (by introducing spawn) but then leave it in anyways. Just let the handle from spawn be ignored and you remove that particular footgun (it becomes a choice to ignore it, which still causes problems but at least the programmer chose to shoot towards their own foot).
