I bet my last 2 cents this has already been raised in past but I want to give it a try and revamp the subject anyway. Is there a reason why the error shouldn't be adjusted to state that *1* argument is actually required instead of 2?
As a function, it does take two arguments, and can be called explicitly that way, no? Adjustment is not enough, the message needs to be substantially rewritten. Something like TypeError: invoked as a method, echo() takes exactly 1 argument (0 given) captures the semantics, but is perhaps too verbose.
