[plt-scheme] for-each being skipped
Andrey,
In your example, you're missing a parenthesis which would close the
lambda expression:
(define (func dir)
(let ([list-of-dirs (filter directory-exists? (directory-list dir))]
(for-each (lambda (val) (create-file-get-string val)) list-of-dirs)
(create-file-get-string dir)))
I don't know if that's really the problem (maybe you just keyed it in
incorrectly).
