Non-prefixed extension properties on UIView feels gross

[bencochran]

Using such generic names in a extensions to UIView and UIViewController feels like recipe for disaster (naming conflicts later, in particular).

Possible ideas:

• Prefix the properties (e.g. pno_left). But that’s less nice looking.
• Wrap UIView in a proxy that defines the properties (in fact ComparableSubject could almost do that now… but ComparableSubject.View(view).left == ComparableSubject.View(label).left is very ugly)
• Use the same proxy idea but somehow pass those into a block that the constraints are created in, Not sure the cleanest way to do this without resorting to a bunch of (UIView) -> [NSLayoutConstraint], (UIView, UIView) -> [NSLayoutConstraint], (UIView, UIView, UIView) -> [NSLayoutConstraint] permutations (variadic parameters have no way of helping as far as I can see)

I’m going to keep pondering solutions to this… (might just going with the prefix, as sad as it makes me)
