[racket] Reading recommendation for static analysis?

Patrick,

"State of the art" in type-checking Scheme is TypedScheme/TypedRacket. I would suggest checking out the relevant papers at the NEU Racket site:
http://www.ccs.neu.edu/scheme/pubs/

For older research on both typing Scheme (e.g. Soft typing) and static analysis of Scheme, I suggest checking the "compilation" page on my Readscheme website:
http://library.readscheme.org/page8.html

Others may have mode specific recommendations... I am bibliographer, not a researcher :)

Cheers,
Jim

I want to write a static analysis tool for a small scheme-like language to catch simple typing errors. The following is a simple example of the type of errors that I would like to detect:
