[racket] Some design "whys" of regexps in Racket

Hello,

I'm curious about 2 design decisions made:

1) Why do I have to escape things like "\d{2}" -> "\\d{2}"?


2) Why there are two kinds of regexps, #rx and #px?
#rx"\\d{2}" doesn't work because the curly braces are part of just pregexps
grammar...
