Possible bug with dereference operator + arrays

[Jarrett Billingsley]

The implicit T[] -> T* conversion disappeared, but there may still be 
vestiges.  You can still dereference an array to get the first element:

int[] a = [1, 2];
writefln(*a);

This is mostly a problem with determining if a type is an array type or a 
pointer type, since is(typeof(*T)) will return true if T is an int[] or if 
it's an int*.
