Well, what do you want to use it for?
It lets you retrieve the 31-bit representation used for a poymorphic
variant or method tag. This is useful if you want to access
polymorphic variants or objects from your C code.
Note that this hashing function is fixed, so depending on your
performence requirements you might want to compute the hashed values
before compilation, and completely drop the string representation.
