I'm just happy that D was mentioned. Yay, D! Also, D's metaprogramming is an utter joy, almost lisp-like, without the craziness of C++ templates. Give it a try! An intro to one ingredient of the magic of D metaprogramming, compile-time function evaluation: https://tour.dlang.org/tour/en/gems/compile-time-function-ev... An example of the kind of introspection available in the D stdlib: https://wiki.dlang.org/Finding_all_Functions_in_a_Module This one's really cool, a library that lets you build an entire grammar of your choice and evaluate it at compile time: https://github.com/PhilippeSigaud/Pegged Nim's metaprogramming seems quite similar, and I sometimes wonder if perhaps it took some inspiration from D.
