> Implementation-recipe design patterns only need to exist (or, rather, only need to be part of the active, day-to-day awareness of more than a small number of programmers per language) when the target language does not support implementing the common solutions as reusable code modules because doing so would require a kind of abstraction the language does not support. False. Lisp has macro's and can abstract anything syntactically, yet still has commonly recurring design patterns such as with-X macros. You misunderstand what a design pattern is if you think new language features can remove the need for them.
