      //
    
      //   1. It is possible to make a user-defined type work with
    
      //   {ASSERT|EXPECT}_??(), but that requires overloading the
    
      //   comparison operators and is thus discouraged by the Google C++
    
      //   Usage Guide.  Therefore, you are advised to use the
    
      //   {ASSERT|EXPECT}_TRUE() macro to assert that two objects are
    
      //   equal.
    
      //
    
      //   2. The {ASSERT|EXPECT}_??() macros do pointer comparisons on
    
      //   pointers (in particular, C strings).  Therefore, if you use it
    
      //   with two C strings, you are testing how their locations in memory
    
      //   are related, not how their content is related.  To compare two C
    
      //   strings by content, use {ASSERT|EXPECT}_STR*().
    
      //
    
      //   3. {ASSERT|EXPECT}_EQ(v1, v2) is preferred to
    
      //   {ASSERT|EXPECT}_TRUE(v1 == v2), as the former tells you
    
      //   what the actual value is when it fails, and similarly for the
    
      //   other comparisons.
    
      //
    
      //   4. Do not depend on the order in which {ASSERT|EXPECT}_??()
    
      //   evaluate their arguments, which is undefined.
    
      //
    
      //   5. These macros evaluate their arguments exactly once.
    
      //
    
      // Examples:
    
      //
    
      //   EXPECT_NE(Foo(), 5);
    
      //   EXPECT_EQ(a_pointer, NULL);
    
      //   ASSERT_LT(i, array_size);
