//$namespace: null !default;

//$#{$namespace}variable: value;

// Want output like:
// $namespaced-variable: value;

// Reasoning:
// I'm building a scss/css framework
// and started realizing that variable
// names like $base-font-size might 
// cause conflicts for people.
// I could just namespace all of my
// variables, but I personally hate
// namespacing in my own stuff so I
// want it to be optional. Would like
// a $namespace variable that is set
// to null !default
// If someone wants a namespace on
// all the variables, they just change
// that variable to a real value and 
// everything has a namespace now.

// You can see a similar approach to
// namespacing selectors here:
// https://github.com/ScalesCSS/base-forms/blob/master/_forms.scss
// line 12 and line 41

// If I can do this with maps, I'm
// missing how.
