It would be really useful to have a str-split($string, $delimiter:" ") function akin to JavaScript, or Ruby.

The primary use case I run into is splitting selector strings i.e.

.foo .bar { /* code */ }

It’s rather difficult to get .bar from & without boilerplate string functions or importing something like sassdash.

A another use case I run into is remove part of selector. As it stands selector-replace does not allow you to remove part of a selector (i.e. replace it with "" or null). Being able to easily split selector strings would makes this much easier.

+1 for a str-split or selector-split function

(Sorry, deleted my comment as it was redundant.)

Maybe a selector-split function would be more appropriate? Something that splits based on combinators:

$test: selector-split(".foo .bar", " ");
// => ((.foo,), (.bar,))

$test: selector-split(".foo .bar > .baz", ">");
// => ((.foo, .bar), (.baz,))
