super slow on windows
There is Only One. En garde!
I never asked for native compilation implemented via the trampoline technique, which increases attack surface (because it causes Emacs to routinely execute files in a known-by-attackers location in my home directory) and makes debugging harder, but I'm stuck with it if I want my Emacs to speak the Wayland protocol (and I do).
Ditto the clumsy bolting-on of lexical scope.
It also has nothing to do with Wayland.
And what's wrong with adding lexical scope!?
I do have some concerns about certain features but the ones listed do work, and work great.
