RfD and RtOG both describe /Core 2.3, and at least two of these

Whether for good or ill, often HELP and SOURCE are the most
up-to-date information. The 2.5 release notes (HTML) at
http://www.rebol.com/docs/core25.html
mention CONTEXT in section 11 and HAS in section 13. I don't
recall at the moment when DOES was added. However...
"Use the SOURCE, Luke!" ;-)
Try copying the following into your interpreter window:
help context
source context
help does
source does
help has
source has
Too much thinking in c? ;-)
