I wonder that too. I haven't got any sensible explanation.

I think they should be preserved (except for the CAPITALIZE stuff), but
better specified. An easy solution is to define it in terms of the

I don't see the problem here. They are defined in terms of CHAR<?, and
CHAR<? does refer to CHAR->INTEGER in R5RS (page 29).

I think it's a good idea to define everything in terms of the character
procedures in R5RS (section 6.3.4).

I wonder if it's really nessesary at all. Is there really a need to
concatenate so many strings that (apply string-append list-of-strings)
doesn't work? What is the lowest known limit on number of
arguments to procedures in a sensible Scheme implementation?

I do agree.

I think it can be useful, but it hasn't much to do with string
processing. The SUBSTRING? procedure is probably better implemented
with Boyer-Moore. Remove the KMP stuff from this SRFI and perhaps make
a separate SRFI with it.

Me too.
