Hmm. No. 

(1) This list is for developers, and they can be beginners too. On
    r-help we cannot even assume that people know that C is a
    programming language.

(2) The author of rpart() had been using a couple of nifty but
    unorthodox tricks that it is not unreasonable for beginners to be
    confused by.

(not disagreeing that reading the documentation is generally a good
idea, of course!)
