But "lambda" (if you're referring to the Python keyword) and "for" are fundamental. Iota isn't. The author of the article insists that iota comes from APL, where perhaps it is fundamental. I don't really appreciate the relevance, since C++ isn't close to being APL, and it seems like it's one of very few concepts taken from APL. It comes across a homage to Ken Iverson's APL more than anything, which makes it seem arbitrary.
