But the match result object is not available within a replacement closure
function, hence the question. At least in ES3, arguments[0] is a string
primitive containing the entire match (i.e. backreference zero). It could be
changed to a String object and have the named backreferences attached to it
as properties (which is how I handle the issue in my
http://stevenlevithan.com/regex/xregexp/ XRegExp library), but this is
fundamentally a different thing, and might have some obscure potential for
compatibility issues.
