Working with state classes

We are using this library in 2 of our projects and works really well.
But one of the practices that we usually use are "State classes" like http://smacss.com/book/type-state

for example if we have

<div styleName="menu__item"></div>

this element can sometimes have this class

<div styleName="menu__item is-active"></div>

To try to style things like this we had to use multiple modules and have a CSS like:

.menu__item {
  color: red;
}

.is-active {
  color: blue;
}

ideally we would like to use

.menu__item {
  color: red;

  &.is-active {
    color: blue;
  }
}

But ok we can more or less work, the problem is when you have something inside menu__item

<div styleName="menu__item is-active">
  <i styleName="menu__icon"></i>
</div>

In that case we cannot do that:

.menu__item {
  color: red;
}

.is-active {
  color: blue;

  .menu__icon {
    color: yellow;
  }
}

or ideally:

.menu {
  &__item {
    color: red;
    
    &.is-active {
      color: blue;
     }
  }

  &__item.is-active &__icon {
    color: yellow; 
  }
}

Are you planning some feature to "disable" selectors that start with a prefix?
For example, for us can be useful to ignore "is-", "u-", etc...

El issue menciona el uso de styleName y selectores CSS anidados, pero no archivos del repositorio ni tests. Empieza localizando el punto de entrada de la transformación de styleName y los tests existentes de resolución de selectores; se considera terminado cuando se puedan ignorar clases de estado con prefijos como is- y u-, mientras los selectores anidados menu__item/menu__icon se resuelvan como se muestra.
