A potential rewrite of the toura.component function

toura_component.js

toura.component = function(name, proto, opts) {
  var ancestors = [toura._Component];
  var namespace = opts.namespace || 'client.components';
  if (opts.ancestors) {
    // concat is a synonym for "push" when fed a non-array
    ancestors = ancestors.concat(opts.ancestors);
  }
  var p = dojo.mixin(proto, {
    templateString : proto.componentTemplate || '%div',

    prepareData : function() {
      this.inherited(arguments);

      if (proto.prep) {
        proto.prep.call(this);
      }
    },

    postCreate : function() {
      this.inherited(arguments);
      if (window.jQuery) { this.$domNode = jQuery(this.domNode); }
    },

    startup : function() {
      this.inherited(arguments);
      if (proto.init) {
        proto.init.call(this);
      }
    }
  });

  dojo.declare(namespace + '.' + name, ancestors, p);
};
