Even if it worked it is awful code.
In serious programming you code not only for yourself, but also for others who will maintain your code.
Playing tricks like this must be avoided, because you respect your colleagues.
One consequence of this code: whether the pointer is NULL or not is even not at question, but it implies that this member kType may not be a plain non-static member of the class. Sometimes classes are big (this is evil too) and one cannot always recheck the definition of each and every variable.
Be rigorous. And call all your static members only this way:
Foo::kType
Another possibility is to follow a coding convention that let know that the member is static, for example, a s_ prefix for all classes static members:
Foo::s_kType
