I previously tried an approach to scope bindings from var to scope but it didn't catch all cases. This is evident in this bug: https://phabricator.babeljs.io/T2892 Where even after transforming a const to a var we still get an error that it's read-only. This approach will go through and delete every existing let and const binding and creates a new one with the kind "var"
