A new command-line option -Wlogical-not-parentheses has been
added for the C and C++ compilers, which warns about "logical
not" used on the left hand side operand of a comparison.
bool not_equal(int x, int y) {
return !x == y; // warn here
}
return !(x == y); // first fix-it, to negate comparison.
return (!x) == y; // second fix-it, to silence warning.
I'll wait for your opinions before asking for this error in D.
New warnings -Wsuggest-final-types and -Wsuggest-final-methods
helps developers to annotate programs by final specifiers (or
anonymous namespaces) in the cases where code generation
improves. These warnings can be used at compile time, but they
are more useful in combination with link-time optimization.

I have added this to Bugzilla, it can please the "final on
default" crowd:
