::: I do not see how any system of references will enable writing
:::                 *fill(*descriptor)
::: any faster.
:: How about         fill(descriptor)  ?
: "This does not compute."  The module which produces the contents of
: fill and descriptor is compiled separately from the one that calls it.
: In addition, I specified that there may even be run-time changes, which
: the calling module does not know.

As I have attempted to point out three times now, one can write

         fr(dr)        instead of           *fp(*dp)

because the *declaration* of a reference makes the indirection
implicit during use, while declaration of a pointer does not.
Either notation can have *all* of the properties mentioned
by Herman Rubin above.

This means that reference notations are identically fast, will map
identically to machine instructions, yet are more flexible to change
(since changes can be introduced at the definition site instead of at
every use site), and involve a simpler notation at the use site.
