[swift-evolution] Standard operator precedence

Very well. May I ask what the rationale might be? I'm not sure I can deduce
it from the available documentation. In other circumstances where Swift
operators differ from C (e.g. overflow handling for addition, etc.), the
behavior is amply documented and the rationale quite clear. (I should add
that Swift documentation currently introduces these bitwise operators as
'familiar' to those coming from C and Objective-C before defining what they
are, which discourages careful study.)
