Situation where serialized attributes might be necessary in Typhoon

gistfile1.aw

<?php

/**
 * My awesome function that does amazing things
 */
function doSomeAwesomeStuff($foo)
{
  // creating a custom type for the foo attribute
  // passing some special matcher object which does the validation work
  $fooType = new CustomType(array(
    'matcher' => new Matcher,
  ));

  // assert it with Typhoon
  Typhoon::assert($fooType, $foo);

  // now assume it fails...
  // we need to throw a nice exception message
  // something like Unexpected value of type 'string' - expected 'CustomType(matcher: '%O:7:"Matcher":0:{}%')'
}
