This string mixin generator allows one to create tagged class reference inside structs and classes.
A tagged class reference uses the bits known to be zero in a normal class reference to store extra information.
For example, a pointer to an integer must be 4-byte aligned, so there are 2 bits that are always known to be zero.
One can store a 2-bit integer there.
The example above creates a tagged reference to an Object in the struct A. This expects the same parameters
as taggedPointer, except the first argument which must be a class type instead of a pointer type.
