Thread starts here

BartC asks for switchable syntax:
https://mail.python.org/pipermail/python-list/2015-April/701998.html

Dan Sommers understands that "you want Lisp, the programmable programming language." : https://mail.python.org/pipermail/python-list/2015-April/702018.html

Subsequent would show that no one really understands what lisp is about
or even the possibility of  'switchable syntax'

The broader picture(s) is fine; I was asking specifically about the fontlock
Is it vanilla FL or have you done something to make the name of the facename
have the color named?
Because it is exactly this kind of 'introspection' that that thread (non)understands
