Operator precedence -- a thought question

Hal E. Fulton

Hypothetically, suppose one wanted to introduce a new operator into
Ruby. And suppose one wanted to decide on a precedence for it.

How would you proceed?

Sure, I'm being vague. Deal with it. :)

In true Ruby spirit, how about picking the precedence which is least
surprising? Especially if this operator is already available in other
language(s) and a precedent for its (umm) precedence exists.

Arbitrarily.

mh.. I think you should go with the precedence it has in another
language if it is imported from there. Other way, do what you want :)

Btw, this makes me wonder what the heck you're doing..
It seem there is some room for a RubyMutations[1] page now :)
