title: SimpleTest: assertEquals and PHP types
body: <p>Considering the following code:</p>
  
  <pre><code>&lt;?php
  class Foo extends UnitTestCase {
      public function testFoo() {
          $foo = new Foo();
          $this-&gt;assertEqual('2, 3', $foo-&gt;bar(3));
      }
  }
  ?&gt;
  
  &lt;?php
  class Foo {
      public function bar() {
          return 2;
      }
  }
  ?&gt;
  </code></pre>
  
  <p>'2, 3' == $foo->bar (2) because PHP allow that. This test pass! But it is wrong in some cases ('2, 3' string is different from 2 integer.</p>
  
  <p>SimpleTest test method from EqualExpectation class:</p>
  
  <pre><code>function test($compare) {
      return (($this-&gt;value == $compare) &amp;&amp; ($compare == $this-&gt;value));
  }
  </code></pre>
  
  <p>Is there a method to test that in SimpleTest? Instead of ==, a method that uses === ...
  Thank you.</p>
