[ruby-core:49235] Re: [ruby-trunk - Feature #7328] Move ** operator precedence under unary + and -

Can I just point out that everyone is using asterisks and carets and
arguing about standard mathematical notation?

I reckon the biggest factor driving this discussion should be existing
behaviour. Changing how operators behave is probably the single biggest
thing that defines and thus changes a language.

If you were writing a new language, however, I'd find this disussion and
its outcome fascinating.
