I propose changing 'regexp' to 'sre-regexp' for future consistency with 'pcre-regexp'.

There will be no `pcre-regexp'. All of the functions in

this SRFI will work with the regexps compiled by `pcre'.

That is, there is only one compiled regexp type.

I am confused. I thought 'regexp' was a procedure which took a <sre> and compiled it into an <re>. And I though 'rx' was syntax which expanded into (regexp '(: <sre> ...)).

Hmmm.... The 'rx' syntax could compile the regular expression at program compile time and just expand into an <re>. Why not be able to do the same thing for PCREs? Hence, 'pcre' syntax which isn't necessary to quote the <pcre>, but is necessary so that a system could compile the regular expression at program compile time rather than just expanding into (pcre-regexp <pcre>).
