try is like the propagation/? operator in Rust:

Given a result tuple, it either evaluates to the (:ok, value) in a success, or returns early with an (:err, msg) tuple.

Easy enough! (And it does this not at the function level but at the block level.)

One question is what it should do if it doesn't get a tuple. Two options: panic! or return that value.

`try` is like the propagation/`?` operator in Rust: Given a result tuple, it either evaluates to the `(:ok, value)` in a success, or returns early with an `(:err, msg)` tuple. Easy enough! (And it does this not at the function level but at the _block_ level.) One question is what it should do if it doesn't get a tuple. Two options: `panic!` or return that value.
