Why use properties instead of setters/getters?

Slightly off-topic @algernon: Why do you prefer properties (puplic class members) to inline setters/getters? The latter would make printf-style tracing of value changes (when there is no debugger available) and assert-based invariant checking applicable at no run time costs. Moreover, they allow for value clamping and change notifications/hooks, if needed. Setters and getters are easy to define via macros without degrading readability, as e.g. done in the vtk project.
