What I don't like about Racket (former PLT Scheme) is that it's a closed environment. You can't use common Scheme libraries (for instance: SLIB), debugging facilities are hidden into Racket's editor therefore you can't access them from Emacs or other tools, etc.

There are some tools available for command line debugging: http://docs.racket-lang.org/errortrace/index.html?q=debuggin... http://docs.racket-lang.org/unstable/debug.html?q=debugging

SLIB has worked in the past. If there are specific parts of SLIB you need, try asking the mailing list for help.
