Hello Sean, SOD> TrueClass responds to "clone" but when you call it, the method just throws an SOD> error that says "can't clone TrueClass." How can I tell when an objects SOD> support a given method if they implement them but then raise exceptions? Is SOD> there some other methodology I should use? Can someone tell me why we can't clone "expanded" objects like booleans, integers, ... ? Wouldn't it be better to simply return the "same" boolean, integer, ... ? -- Best regards, emailto: scholz at scriptolutions dot com Lothar Scholz http://www.ruby-ide.com CTO Scriptolutions Ruby, PHP, Python IDE 's
