We can turn the regular expression into a concise ABNF grammar if that
helps, we might also adapt it if that is found to be necessary, but I do
not see a reason why hundreds of lines of prose code or JavaScript code
would help (and anyone who would like to have that anyway can easily de-
rive it from the expression or from a grammar).

I note that I have not seen much commentary on what's wrong with using
the regular expression for fault-tolerant parsing, I've mostly seen the
usual distractions like pointing out how it's not normative. There are
some problems with it in that it leads to behavior that is inconsistent
with some implementations (does "$:" have a scheme of "$" where "$" is
a character not allowed in the scheme componant?) How would we get from
here to talking about such issues, if we want to address this at all?
