I just submitted a new revision of the SRFI. The revision redefines default values thus:
hash-table-ref and hash-table-update! get a(n optional) thunk. There are variants, hash-table-ref/default and hash-table-update!/default, that get a default value. If nobody opposes this scheme, I'll ask for the finalisation of the SRFI.
