RT expressions are like regexes for matching sexprs, rather than matching strings. http://library.readscheme.org/servlets/cite.ss?pattern=sw2004-bagrak If I'm not mistaken, Olin Shivers, one of the principal authors, also designed the SRE syntax.

It wouldn't be at all hard to port them to Chicken or even rewrite them from scratch, as all they do is process the S-expression and return a string containing the equivalent PCRE, being sure to do all the escaping that's needed.

We use guile for our scheme init scripts, and the (ice-9 regex) module also implements the API but not the syntax. Its not like it would be slower running regexps defined that way, you have to compile them anyway if you intend to use them with any decent speed... perhaps just lack of developer time :) I've been wondering that myself.
