I've seen beginners make the mistake of calling f(c, a, b) and being
confused why it doesn't work the way they expected, so I think the newb
trap might go in the other direction. If by "newb" one means "totally new
to programming" then I think the keyword style is probably less confusing
but if you come from a language with only positional arguments (admittedly
most languages!) then the trap goes in the other direction.
Of course, I don't have the resources or time to make a study about this to
figure out which is which, but I agree it's an interesting question.
