Allow returning from infinite loop

[jaredkrinke]

If I have a function that's an infinite loop that only exits via a "return", I get a compile error stating that there isn't a "return" at the end of the function. It would be nice to support that to avoid having to capture the return value in a variable, break, and then return the value.

Of course, if that complicates the implementation too much, it seems reasonable to not support this.

I'm pretty sure this is in my internal backlog. But let's also keep this issue so it's more visible.

I am currently in the big rewrite process so it could take a while before I could get to quality of life features (but I might look into this earlier).

For now you can put unreachable; after the loop which should compile properly.

No worries. I don't want to waste your time or anything--I just noticed a few things while playing with LO for a Project Euler problem and thought I would share what I ran across (in a couple of issues and discussion threads, as seemed appropriate). Feel free to ignore, add as TODOs, correct my understanding, etc. as you see fit.

If I was in the middle of a rewrite, I would probably just make a note to double-check any of these that seemed important after the rewrite was mostly done.

Your 100 problems repo looks pretty impressive :)

I also appreciate you taking time to contribute to LO 🤝
