[swift-evolution] Abstract methods

[C. Keith Ray]

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.
