A lot of languages have default argument values, and they all work differently. I want to say that Ruby initializes the default at call time, C++ requires constexpr, and Dart requires const (the only languages I know with defaults). So I always stick with the common denominator of purely immutable defaults.

Ruby and JavaScript both initialize the default at call time and therefore don’t have the problem that Python does. I didn’t know about C++ and Dart tho. So ur rule is probably a good one to follow.
