[Chicken-users] Review my Caesar Cipher?

[Daniel Carrera]

Hello,

I found a Scheme implementation of the Caesar cipher on Rosetta Code. It said "This was written by a novice, please review"... So I reviewed it, and basically rewrote it.

I think my version is much better (clearer) but since I too am a novice, I feel bad removing the "novice" warning. Could someone who has used Scheme longer than two weeks have a quick look at my work and tell me if I can remove the warning (or make corrections if my code is not idiomatic or something)?

My version(s):

http://rosettacode.org/wiki/Caesar_cipher#Scheme

Previous version:

http://rosettacode.org/mw/index.php?title=Caesar_cipher&oldid=177675#scheme

Cheers,

Daniel.
