Sass Function to determine if a string has quotes

There’s currently no way to check if a string has quotes. I suggest we add:

has-quotes($string) => true/false

I really really needed this, so I wrote a polyfill that uses an interpolation quirk, probably don’t use this, lol.

// @author Brant Wedel
// Check if a string is quoted
// polyfill for str-is-quoted that might be native in sass >= 4.0.0
// Uses concatenation (bug?) in interpolation to test for string quotes
// works in libsass/sass >= v3.4.25
@function str-is-quoted($string) {
    @if type-of($string) != string {
        @error("$string: #{inspect($string)} is not a string for `str-is-quoted'");
    }
    @return "#{$string#{''}}" != $string;
}

@yairEO You don’t need quotes here, you need parentheses.

$typography : (
    font-family    : (Roboto, Arial, sans-serif),
    base-font-size : 14px
);
