The problem is the jslint nasty is REALLY nasty (i.e., every use of this function requires /*jslint bitwise:true*/ & /*jslint bitwise:false*/ wrapped around each invocation). The runtime costs here would be measured in amounts far less than 1ms.

I don't believe that the performance gain is even measurable, but the clumsiness the jslint overrides introduce around usage definitely would be frustrating. Thoughts?
