That depends on what a is. If it's an AA as in the OP, then yes, they should 
be the same. The same goes for a pointers to built-in types and arrays, but 
for classes and pointers to structs, assert(a) checks for null and then calls 
the class' invariant rather than just checking for null. However, the 
invariant does not get called for if statements.
