Yes, and as we all know, the documentation is *always* kept up to date.

There is a separate mailing list for REXML, and I get quite a number of direct 
correspondances, as well.  I'd guess that less than 10% of the REXML 
discussion occurs in ruby-talk.

I can forward emails, if you like.  They're mostly not complaints about the 
hash-ed nature of the arguments, but rather "how do I do this", and "I can't 
get this to work", and "how does this work?"

The problem is in handling polymorphic methods.   Ruby doesn't support method 
polymorphism, meaning that to have method foo() that takes EITHER a string 
and an optional int, OR a Foo and an optional String and an optional int, I 
have to produce some pretty complex code to handle the various possible 
states.
