François Remy pointed us to a document:
http://tabatkins.github.io/specs/css-extend-rule/ , this project aims at
doing the same thing you had in mind: custom classes. But the syntax will
be in the form of
%custom_selector {}
instead of
--custom_selector
and at present the custom class call (let's say "placeholder" instead of
"custom class") is supposed to be made through this syntax:
#selector {
@extend %custom selector
}
I guess it's improvable, but let's wait for answer from the author :)
Cheers,
Andrea
