I completely agree with this. These are pretty simple and straightforward features (at least from the perspective of the user. I guess the compiler's perspective matters more) for how useful they are.

+1. These are very convenient features which I use all the time, and they don't seem to be very large/extensive to cause feature bloat.

I am a fan of letting in tuple indexing - still unsure about if let though :/

[arcto]

+1. I use them every day.

We (the Rust team) have discussed this and decided to merge it.
