Fortunately it's possible to have a really smooth deprecation here, warning only for un-parenthesized uses of
a<<b*csyntax, which I think makes this change quite palatable.Another motivation for this change is that
1//2<<3parses as(1//2)<<3, but there are no methods of<<forRational--- it's practically a method error built in to the syntax! This also makes the deprecation easier since we don't have to worry about those cases.
