IIRC, the implementations were done in C++.

I don't know how reasonable that is.I think their original background was Smalltalk, which is a very dynamic language.
I've heard that before (from a Lisp guy, surprise!). I think it was Paul Graham (see here[1]).There is this common idea that 'patterns compensate for language limitations' but this seems unnecessarily harsh.
They are a way of looking at components of a *design* at a higher-level. It's a lot easier to do these things in Lua, but they are still useful tools for thinking. Would be interesting doing a wiki page and systematically going through the patterns: http://en.wikipedia.org/wiki/Design_Patterns#Patterns_by_Type A quick look indicates that only a few are specific to classic statically-typed languages. steve d.
