[racket] any korean speakers who can localize racket keywords?

As an demonstration and experiment, I'm trying to make a Korean
version for whalesong, where some of the keywords have Korean
equivalents.

Unfortunately, I have no idea if the keywords I've chosen make any
sense, as I'm blindly using Google Translate.  Can someone double
check that the keywords are locally correct?


Yes, I know, I really should know this, but I failed badly at learning
the language in my Korean school... :(
