It's both ;-)  One of them is my real-life last name, as can be found
on my ID or on copyright notices, while the other is a pseudonymous
last name I've been using over the internet for something like a
decade now. While it was never intended to more than a thin pseudonym,
it was supposed to require a little more research to make the
connection, here I just messed up with Google accounts (I really hate
these browser interfaces, and now it makes me hate them even more, I
wish I could find a NNTP server and a real user-friendly text-mode
news reader).

Is one of them more standard than the other? While I'm very familiar
with regex, I only have a few theoretical notions about grammar, and
almost nothing as practical experience with real grammar formats.

I can assure you what I'm doing is completely conform with Rivest's
standard proposition. I don't know how come it has not reached the
status of full-fledged RFC (while real RFCs like SPKI do depend on
it), but I'm using it as if it had. I only dropped the "display hint"
stuff from the format, because I find it little to no use, while it
introduces quite a bit of complexity.

However I have no idea how things look like from a lisp point of view.


Hoping this helps,
