Okay, here's my 2 cent quiz:
Define a reader macro that reads strings but treats backslashes as normal characters, except if you escape the string terminator. This should work sort of like Perl's single quote string syntax:
Perl:
$pattern = '\w \s'; # five characters
Lisp:
(let ((pattern #"\w \s")) ; five characters ...)
as opposed to
(let ((pattern "\w \s")) ; five characters ...)
but this works:
(let ((pattern #"\w " \s")) ; seven characters ...)
The #" syntax is just to give you an idea of what I want; you can use whatever macro character(s) you like.
Send answers to the list, preferably with at least one working test case displayed, e.g. something like
cl-user> #"\w " \s" "\w " \s"
cl-user>
-- L
(Yes, this is similar to a previous quiz. Sue me.)
