    Hello list,

    I am writing an interpreter for a simple language in O'Caml.
    The interpreter often needs to search a hash table with a string
    as key. A common optimization for this is to use pointer identity
    instead of string equality, and "intern" every string before using
    it as a key to the hash table.

    Unfortunately, I don't see how to do this with the current O'Caml
    libs. You can do identity checks with ==, but there seems no way
    to get a good hash corresponding to ==.

    Has anyone already written some code for this task?

    Thanks in advance,

    Stephan
