beta.1 throws on /deep/ selector

[daniel-v]

Angular 2 emulated view encapsulation gives special meaning to /deep/ selector. This is true for TS and Dart versions as well. https://webdev.dartlang.org/angular/guide/component-styles#!#special-selectors

Expressions such as:

:host /deep/ .expected-optional-class { }

is valid and is a recommended way to deal with certain use-cases. Would be nice if dart-sass supported it.

This is intentional. The /deep/ syntax is not in any current CSS spec, nor has it been for some time. Its replacement, >>>, is explicitly marked as "invalid when used in stylesheets". Chrome support for /deep/ in stylesheets "being deprecated".

This makes dart-sass unusable with Angular (Dart and TS)

@matanlurey do you have any thoughts on this?

@nex3 and I have settled on using ::ng-deep in AngularDart 4.x.

We can back-port and release 3.2.0 to make this available to AngularDart users sooner. Follow:
