One proposal is to make char and dchar comparisons illegal (after 
all, they are comparing different things - an UTF-8 code unit 
with a code point, and even though in some cases this comparison 
makes sense, in many it doesn't). That would solve most silent 
breakages at the expense of more not-so-silent breakages.

Shameless self-promotion alert: An alternative is a GitHub fork. 
You can easily install and try out D forks with Digger, it's two 
commands:

digger build master+jmdavis/phobos/noautodecode
digger install
