That's kind of an inappropriate response. Pointing out one has implemented Scheme with all the bells and whistles as a condition in which the implementor is still interested in Lisp implementations and similar stuff is not a pretension or a statement that it was some kind of tremendous feat.
I have a motorcycle, but I'm still interested in not only other motorcycles, but also bicycles. I don't think this makes me a pretentious douche.
