Document panic=abort limitation

I'm hesitant whether to accept this PR. I have plans to amend iex to support panic=abort environments by switching back to Result, so this passage won't stay for long. I also don't think publishing a patch version just for a doc update is a good idea, so I'm not sure if it'll ever see the light.

I think I'll leave this issue open as a reminder to me, but won't merge it yet. Feel free to barge in if you feel leaving it in the current state is misleading and dangerous, though.

That's fine. I like turning iex::Result into std::Result when unwinding is not supported . How do you detect the ability to unwind at compile time on stable?

Alternatively, you could merge now without creating a release. If you address the issue before the next release, remove the comment.

I think I'm less likely to forget about it with an open issue/PR. Thanks anyway!
