Yes, sorry -- it wasn't meant as a rebuttal to what you wrote.
It's also likely that regexps in the suggested "raw" string literals would be inferior to what Python and Perl offer for reasons Stefan Monnier already mentioned. The basic string regexp syntax would need a complete change to even come close -- and then we have two slightly different string regexp notations.
Anna, I'm ashamed for welcoming a new friendly contributor as Mr. No. In a weak attempt to compensate, here are some related areas in Emacs that might benefit from your energy and skill:
* [Easy] There is currently no build-in way to print the string " \t\r\n" exactly that way -- the best we can do (setting print-escape-newlines and print-escape-control-characters) is " \11\15\n" which isn't as readable. Introduce an option to the Lisp string printer so that common control characters print as their special backslash sequences: \t, \r, \b, \e, maybe \a and \e, maybe not \v.
* Improve interactive regexp use. Maybe a user could configure a preferred regexp syntax (standard Emacs, PCRE, rx, etc) to be used when doing interactive search and replace. It would also affect how regexps are displayed and edited in customisation dialogues; right now, they are often difficult to read. Ideally a user should be able to switch syntax during entry at any time and have the regexp translated. Can syntax colouring (font-lock) improve regexp entry and display?
I'm sure other people have more suggestions (and I have some more demanding items should you wish for something chewy.)
