I believe that's correct. Code in question is here: https://github.com/clojure/clojure/blob/master/src/jvm/clojure/lang/Compiler.java#L4358-L4360 > 2) It seems methods defined inline on deftype are different then the ones > defined with extend.

Inline are compiled onto the class, extended (note, this is protocol-only) are external functions. Protocol method invocation uses a cache when determining the correct impl so while there is a performance difference but it's unlikely to be a critical factor in most cases. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
