[racket] TLS "atom?" definition for Scheme does not work in DrRacket

Daniel


Thanks for your interest.

Any reference to any definition (supposed) from the I-pane throws an
"undefined" error; there are no apparent errors when click Run
immediately after I load the definition file. I'm not going to worry
about it too much at this point. It's probably a simple noobie problem
and my main thrust is to get through TLS as effectively (maybe not as
fast) as possible and I think the "racket" spec will let me do that.

If I get sand-bagged by TLS I'll probably try setting up a new
definitions file with only one or two lines and seeing what I can promote.

Does this mean that when you try to reference a defined value you get an error? Or what exactly is happening when you try to use one of your definitions in the interactions window?
