In a system that uses random-access lists everywhere, you would not need
conversions. In a system that doesn't, these are easy to portably
define. So now I'm not sure what your concern is.
I want to be able to write portable programs that can take advantage
of systems with only random-access lists, but that can run on other
systems as well by converting between sequential lists and random-
access lists. `Take advantage' here means using identity conversions.
Of course I can define copying conversions portably and use those, but
that wouldn't take advantage of systems whose lists are all
I see; I will add these operations in the next iteration. Thanks.
