I'm confused by the term. I don't like it one bit. "Early binding" of a default value seems to mean that the expression that produces the default value of a function parameter is evaluated when the function is defined. "Late binding" seems to mean that the expression is evaluated when the function is called. In both cases the actual binding of the parameter to the value (either the default or an actual argument) is established when the function is called. Several different bindings of that same parameter to different values can hold simultaneously, so the *binding* has to be conceptually "late". Because recursion. Why isn't the evaluation of the default expression called evaluation? Or at least something that doesn't already mean something else that is as crucially important as, well, I've already given up on talking about REDACTED and REDACTED in connection with Python, and here I see related established terminology used for something else *for no reason that I can see*. I see no *need* to call this other thing "binding". -- https://mail.python.org/mailman/listinfo/python-list
