OK, I should have said the languages I've looked into (Ruby, Python, Erlang, Clojure, Elixir, Javascript, Scheme, Lisp) get by without version strings specified in the code.

    The Python 2 to Python 3 migration has been incredibly painful, and there are still a huge number of people on Python 2. Ditto for Ruby 1.8 to 1.9.

    Javascript has had a nightmarish compatibility and upgrade story.

    Scheme and Erlang are fairly rigidly specified.

    Clojure is young enough that breakage is treated as expected between versions.

    Lisp is a whole family of languages - but if you mean Common Lisp, it's been extensively tied to an essentially fixed spec for a very, very long time.
