Something that I should have mentioned earlier is that STG has the nice property that all allocation is syntactically obvious: allocated closures manifest as `let`s. This makes it fairly easy to pick out possible allocation sites, even in large dumps.
Ah, that's very useful to know! Armed with that knowledge, I came to the conclusion that the allocation was for the sharing of the `nextState` variable. Inlining it brings it down to 20us and 22kB per iteration. https://github.com/DaveCTurner/json-validator/commit/ec994ec9226ca7bc2e76f19... Getting closer, but it looks like waiting for 8.2 is a better answer. Looking forward to it! Cheers,
