The next dmd update is getting the fruits of this.
Another benefit which you didn't mention in the article is that turning
bugs into __error in this way makes the compiler simpler and more robust.
If you follow the strategy of guessing what the programmer intended, and
ploughing on, you can end up with some very bizarre nonsensical
situations, which are otherwise impossible. The compiler has to deal
with that nasty mess. But, the way to supress cascading errors is by
short-circuiting semantic analysis.
At least a dozen of the compiler faults which I have patched were caused
by this. I think a likely side-effect of these changes will be to fix
bugs which haven't been discovered yet.
