Or more realistically, most programmers will continue to be oblivious,

party libraries written on a PC are unusable on resource-limited
machines, and people like me will waste innumerable more hours
re-inventing wheels in-house, because the programmer of a closed-source
library either didn't know, or didn't give a shit.
None of it would be a problem if he just had to type virtual when he
meant it... the action would even assist in invoking conscious thought
about whether that's actually what he wants to do, or if there's a
better design.

Manu, maybe something you might not be aware:
- Smalltalk
- Eiffel
- Lisp
- Java
- Self
- Dylan
- Julia
- Objective-C
- JavaScript
Are just a few examples of languages with virtual semantics for method
call. Some of those only offer virtual dispatch actually.
Some of them were developed in an age of computer systems that would
make today's embedded systems look like High Performance Computing servers.
Julia is actually a new kid on block, hardly one year old, and already
achieves C parity in many benchmarks.
So I think how much could be a problem of D's compilers and not the
virtual by default concept in itself.
