It's possible that we should provide some advanced version of the API with a struct so that it is more extensible in the future.

Ah, yes, it would be nice to fix that.

The `spawn_blocking` in your first example doesn't really do anything. Did you mean to spawn the sleep to a different thread?

It would be more useful with the svg version of those flamegraphs, because you can hover each bar and see the full label in it.

So, what you're saying is that currently, all of the aliases have a single fixed type except for the `espidf` and `horizon` target OS?

Let's wait for std to stabilize `try_exists`. I'd rather not stabilize this, then see std change the signature of theirs so we don't match.

Sure! I see that it hasn't been released yet, but I would be happy to include our own version of it when that happens.

Unwinding doesn't work on wasm.

Yes.
