Grunt variables not expanded

[luileito]

Grunt variables (e.g. <%= something %>) are not expanded, i.e., they are processed as literals. Is it possible to use these variables? It'd be useful being able to do something like:

clean: {
  js: [ 
    '<%= concat.dist.dest %>',
    '<%= uglify.dist.dest %>'
  ]
}
