CSS Advanced Sass Advanced Directives Using the @each Directive

Should this work in Sass 3.4.12?

I've been working on this example in Sassmeister where Dale uses @each to iterate through a complex list. Here it is

//list of icon names stored in a variable
$icon-names: (strategy '\e002') (twitter '\e003') (github '\e004');

//use interpolation syntax to loop through the list,
//a variable in singular to loop through the plural variable 

@each $icon-name in $icon-names {
  //pull each value from icon names to be a class selector
 .icon-#{nth($icon-name, 1)}:after {
      content: nth($icon-name, 2);  //works in libsass 3.1.0 and 
                                    //sass 3.3.14 but NOT 3.4.12

 } 
}

I'm just looking for confirmation that this is a technique that doesn't work in the latest version of Sass. This example works in in libsass 3.1.0 and Sass 3.3.14 but NOT **Sass 3.4.12

Edit... Sorry I should explain further that this is the CSS output I get when I try this code in 3.4.12. (including the charset.)

@charset "UTF-8";
.icon-strategy:after {
  content: "";
}

.icon-twitter:after {
  content: "";
}

.icon-github:after {
  content: "";
}

thanks. :)

Hi Chris, thanks for letting me know.

Just so long as I know there's nothing wrong with the Syntax. :)
