Hash tables with custom equality test

  Q: Why do hash tables in PLT scheme do not have a parameterizable
     equality operation?

Answer: there is a `make-custom-hash'[1] function.  However, the
hashing operation depends on the equality operation, so this needs
more than just an equality op.

  Q: Is there a hash in terms of `bound-identifier=?' ?
