IMO that's the most important point. If we were to make it a
warning, it would trigger *everywhere* and very often on valid
code. The signal to noise ratio would be terrible, as it
currently is for C++ code.
I really think there is room for improvement, but anything that
would trigger false positive I would strongly oppose. In D I
never feels like I have to please the compiler, because errors
are almost always sane. In C++, you always have to throw a few
compiler switches (`-Wall -Wextra`) and then write your code so
that the compiler is happy. No thanks.
If anyone want an example of bad warnings in D:
