Re: SCSS parser ideas

[Alex Dunn <dunn.alex@gmail.com>]

I think better built-in support for SCSS would be very welcome,
especially since development of both the scss-mode
(https://github.com/antonj/scss-mode) and sass-mode
(https://github.com/nex3/sass-mode) external packages seems to have
ceased.
