Rogue 'panic' -> 'fail' in guide.

Should refer to handling panicking tasks like any other computation
that may fail, not any other computation that may panic.

Thanks for the pull request, and welcome! The Rust team is excited to review your changes, and you should hear from @brson (or someone else) soon.

Hmmmmmmm, I think this one is actually a bit ambiguous! We're talking about Results... I can see this sentence either way. Interesting.

It looks to me like an accidental change from the fail!->panic! rename.

This task will randomly panic or succeed. `task::try` returns a `Result`
type, so we can handle the response like any other computation that may
panic.

I can't parse any reasonable meaning from it this way, given that there is no way to recover a task from panicking.

Whereas the point of task::try is to abstract over the fact that there's a potentially panicky task producing a result, allowing you to use your normal (return value based) error handling machinery to deal with it, just like almost all other non-panic types of failures. So with 'panic' changed back to 'fail' it communicates something meaningful.

I'm trying to find meaning in the sentence as it stands, and I'm failing miserably. (But at least I'm not panicking! 😄)

Thanks @slashgrin.
