Change list separator

It doesn’t seem possible to change the seaprator of a list. I propose a function change_separator or similar.

I found a need for this, as sometimes one is not in control where a list comes from or how it’s created. Using a framework, or using a built-in function that builds you a list like map_values. Sometimes you just always get one separator, when you need to other.

Another option is to give control over how a list is rendered to the output. That is to say, allow overriding the separator when outputting it.

@function set-separator($list, $separator: list-separator($list)) {
  @if $separator == 'comma' or $separator == 'space' {
    @return join($list, (), $separator);
  }
  @error 'Not a valid separator: #{$separator}';
}

$foo: set-separator(1 2 3, comma);
// => 1, 2, 3

And how do I change ONLY the separator, without putting the list through a join function?

Look, I understand you don’t want to cencern yourself with petty issues like this, I get it. But you make it look like I’m just whining. I’m trying to suggest ways to make Sass nicer to work with. If you prefer keeping Sass a more verbose and potentially less efficient language, fine, but then just say so up front.
