...but every addition to make them more powerful and feature-rich is one more step in the direction of blurring the lines between what's code and what isn't, since more and more things that are supposed to be code will be expressed in ways that aren't code at all but fed to an interpreter inside the interpreter. And with every release, the language specification that I'm having to hold in my head when dealing with other people's code grows more and more complex while the cost-benefit calculation around the additional complexity shows diminishing returns.
It kind of goes to the question: When is a language "finished"?
