[racket] I just can't understand readtables

I'm trying to wrap my head around them and be able to use them.
I'm trying to write something for a Clojure compability layer in Github and i just find it impossible to use the make-readtable procedure to start doing something.


Can someone show me the code to make this #"hello" expand to (regexp "hello") ?


It seems something so easy, but i can't figure out how to do it, even seeing examples and the docs, I keep getting byte-strings when i use it.
