Hi, I was poking around the reader while working on the Unicode stuff, and I found that there aren't checks for a lot of symbol names that R6RS considers to be invalid.
The following line has 11 dodgy but not invalid variable names:
+ - ... 00A @ [ \ ] { | }
They can be strung together to make fun code like this:
(define - 1)
(define [ 2)
(define ] 3)
(+ 1 [ - 2 3 ])
==> 12
Which of these are useful extensions and which of these are bugs?
Thanks,
Mike Gran
