reasonable use of defining functions in a loop?

loop_functions.js

function OOPShim() {
}

function proxyMethods(names) {
  for (var i = 0; i < names.length; i++) {
    var name = names[i];
    OOPShim.prototype[name] = function(a) {
      var args = Array.prototype.slice.call(arguments, 0);
      args.unshift(this.state);
      return FunctionalAPI[name].apply(this, args)();
    };
  }
}

proxyMethods('foo', 'bar', 'baz');
