I keep seeing references to those in code samples all over gambit written code. What do they do exactly? I think I know, but they seem to take a plethora of keywords as well constructor:, extender:, implementer: etc.

Sorry about the noise, Pavel P.S. These are somewhat documented on the wiki, but most of the keywords they take are undocumented.

When I was on the R6RS editors committee I wrote a document to discuss the design of a record definition feature for R6RS. It discusses some of the design issues and it explains how Gambit's define-type special form addresses these issues. It's the most complete documentation I have on define-type (except for the sources!). Here it is.
