Have you considered to what extent its interface could
look like std::filesystem::path ?

Back in about 2005 I wrote a URI parser using Spirit, mainly
as an exercise to learn about Spirit's new features.  The code
was compact and directly corresponded to the BNF in the spec.
Run-time performance was good though compilation times were
slow and error messages were horrible.  The main problem I
faced was that the BNF in the spec was wrong!  The RFC had
to be read alongside an obscure "errata" webpage
(https://skrb.org/ietf/http_errata.html) that I didn't
discover for ages.  Anyway, I've had a look at your parser
and... well it's about five times as much code and much
further removed from the BNF.

Regards, Phil.
