[swift-evolution] Abstract methods

How many "subclass must override" assertions or comments in base class methods do we need to see, to want to add "abstract" to the Swift language? 5? 50? 500?

It's a not uncommon idiom in Objective-C.

I'm about to port a substantial amount of C++ code to swift, and compiler help to enforce abstract classes would be very useful.
