I too think it would be a big mistake to allow let patterns to be refutable, when we've already tried and rejected allowing the same in match statements (ancient Rust history quiz: who else remembers `match check`?).
For those of us that were not around or do not remember, can you explain what was tried and rejected?
I sometimes find myself writing a `_ => ()` arm for match and wish it could be implied… and sometimes `_ => fail!()`. That the two are sometimes used is probably a sign that the status quo (require it to be explicit) is better.
