I hate how the pre-tag is not able to take its content literally!

1. ASSERT;
2. assert;
3. _ASSERT;
4. _assert.

Which one is the most correct to use?

I think there is no need to manually define ASSERT and other forms of ASSERT to NULL when in release configuration, right?

if( test != value )
    MyMagicAssert( test )

if( test != value )
