The following code is a syntax error in ES6:
let a = 'something';
let a = 'other thing';
Previously GJS would silently accept this code, but in the next release the
SpiderMonkey JS engine will be more ES6-compliant.

Instead of calling out to gnome-settings-daemon we'll just implement
the switching logic ourselves and use mutter APIs that allow this
functionality to work both in X sessions and when we're a Wayland
compositor.
Switching IBus engines is done transparently as well just like g-s-d
used to do.
