it seems to me quite the opposite. most of these ideas are actually fairly old. they just never got implemented in or were never supported by a widely used language. i've seen very few "new" ideas show up in programming languages, but what i am happy to see is the relatively careful integration of some of the most useful and powerful idioms from other languages (lisp, python and so forth) into a language where i can actually control precisely what happens (C++). it turns out that there are two levels of care: first, those responsible for the std:: namespace (and even boost:: to some extent), and then myself as an individual programmer making choices about what to use.
