Btw, I impemented it in the face of popular support too of course, but personally to the benefit of this feature is not any kind of autoprefixin (which I don't care at all) but an ability to automate whatever property generation. Imagine this (somewhere in the future): `.make-animarion(@property, @base-value, @animation-template-function)` - where `@property` is any property (or even a list of properties), `@base-value` is some base value (or a list) for that property and `@animation-template-function` is some mixin template that defines actuall animation parameters (e.g. curve, number of frames and actual value(s) changes for each frame etc.). This will be impossible w/o "property name interpolation". This is just one of possible use-cases of course (I beleave e'll invent more interesting automating stuff when this goes in).
