D2 is really that stable as it is claimed to be?

The creation of such breaking changes should have priority over 
(= happen sooner than) most other compiler changes and bug fixes.

Beside AAs, scope, and shared, another smaller example of such 
breaking changes was discussed a lot today:

http://d.puremagic.com/issues/show_bug.cgi?id=11080
http://d.puremagic.com/issues/show_bug.cgi?id=4733

In Issue 11080 someone has asked to disallow code like:

assert("something going wrong");

But I suggest to not add that rule and instead implement the 
small breaking change discussed in Issue 4733, that disallows the 
use of dynamic arrays in all boolean evaluation contexts. So 
Issue 11080 becomes a special case that needs no special testing 
code in the compiler.
