I'm familiar with this in Ruby (and Perl, where it originated), and I think that `:` is strictly superior to `=>`. (When Ruby 2 introduced `a: x` as a shorthand for `:a => x`, I jumped on it immediately and never looked back.) The *only* reason to change to `=` is to match dictionary assignment; `=>` doesn't do that.
