There are two really great additions to Elixir 1.2: multi-alias, and matching variables in map keys.
Previously I found myself wanting to alias a lot of things, like:
alias Foo.User
alias Foo.Email
alias Foo.Location
Now with multi-aliasing I can do it all in one line:
alias Foo.{User, Email, Location}
That's just a cool syntactic sugar kind of thing that maybe saves a few lines at the top of the file. But the map key matching is great, and something that I've frequently missed up until now.
