Subject: hash-get-handle and hash-ref redundant
Date: Fri, 29 Jun 2007 16:49:59 -0400	[thread overview]
Message-ID: <46857077.7080808@fastmail.fm> (raw)

Hi,
The procedure hash-get-handle seems to be a less useful version of hash-ref.

guile> (help hash-get-handle )
`hash-get-handle' is a primitive procedure in the (guile) module.

 -- Scheme Procedure: hash-get-handle table key
     This procedure returns the `(key . value)' pair from the hash
     table TABLE.  If TABLE does not hold an associated value for KEY,
     `#f' is returned.  Uses `equal?' for equality testing.

guile> (help hash-ref)
`hash-ref' is a primitive procedure in the (guile) module.

 -- Scheme Procedure: hash-ref table key [dflt]
     Look up KEY in the hash table TABLE, and return the value (if any)
     associated with it.  If KEY is not found, return DEFAULT (or `#f'
     if no DEFAULT argument is supplied).  Uses `equal?' for equality
     testing.

Perhaps one is meant to be used only internally?  I'm guessing that 
hash-get-handle should not be visible.  If the developers concur, let's 
make this change before 1.8.2.
Regards,
Jon
