For example it is nice to be able to chain hash functions
(something that the default one does not allow).
Just overload the toHash() function for your user-defined type to be
whatever you want it to be.
I know, maybe I have not expressed myself clearly, but this overridden
function has to be written.
For objects combining various pieces, one has to create a unique hash
from various pieces.
The functions I have defined in hash.d help in doing that is such a
way that changing a bit anywhere most likely changes the whole hash.
