Sass ignores Compiler Directives

The Sencha compiler supports special compiler directives, embedded in line comments. For example to define a class and one dependency without "Ext.define":

//@define MyApp.Example

//@require MyApp.Other

The issue is that during the build these directives are ignored when creating the CSS file.

The "<build>/temp/testing/sass/MyApp-all.scss" does not contain "myapp-example", which obviously means that the corresponding style definitions won't be part of the final CSS file.

Any suggestions?

Thanks,

Patrick
