Ok.  But don't expect expect at least my Scheme implementation to
put effort into implementing SRFI-63 - at least until we get a
preview of R6RS.

(I do find the lack of openness in the R6RS process rather
unsuitable, FWIW.)

Hm.  Ironically, it was I who pointed out the incompatibility.
But nobody who was actually was using Bawden-arrays spoke up, it
appears.  And it wasn't just "SRFI-25 authors who decided to
be incompatible" - others supported that decision.  I was the
only one (? - I haven't check the entire discussion acrhive) to
argue for compatibility (as I do again), but using Bawden-arrays
myself I could hardly object too strongly.

However, in the current situation I myself have implemented SRFI-25
arrays, so I *am* in a position to object.

SLIB certainly had more users when SRFI-25 was released.

Irrelevant at this point.  What is the usage *today*?

SRFI-63 now be penalized for the SRFI-25 authors' rudeness?

So "rudeness" should be met with "rudeness" - not to mention
exacerbating incompatibility headaches for "innocent bystanders?"

The specification of any linear index mapping by means of a procedure
is a clever synthesis which I doubt predates the 1980s.

That may be the case.

I will reword
the paragraph to emphasize the arbitrary linear mapping aspect.

I doubt arbitrary linear mapping are original with Bawden - but
expressing them using a procedure might be.

I am unfamiliar with Q; please send a citation if you think it should
be cited.

Probably not appropriate.  I was just using it as an indication to
suggest that arbitrary linear mappings predates 1993.
