Well, if so, it is my increasingly strong judgment that requiring another programmer to junk up his or her code with make_person(name=name, age=age, phone=phone, location = location) # instead of # make_person(name, age, phone, location) # or * make_person(name=person_data[0], age=person_data[2], phone=person_data[3], location=person_data[3]) # instead # make_person(*person_data) is generally unreasonable. Remember, any person who actually prefers to write the longer forms is free to do so. > Since we're all consenting adults, That is the basis for my objection. Most of the 'reasons' given for imposing the longer forms above have been about *not* treating function-calling programmers as fellow consenting adults, or rather, about treating them as non-adults. One exception is the claim that in the alpha phase of a library project, the developer might be willing to freeze parameter names before freezing parameter positions. But this should be rare, temporary, and might be dealt with as well by the common procedure of stating that function signatures (APIs) are subject to change, while indicating which aspect are considered most stable or unstable. > we should have the tools to make our judgements easy to apply.

I do not see the logic of this statement. I could just as well claim that it is constraints that require action, and which are therefore, in a sense, optional, that are disputable issues.
