If I have series of statements such as

throw new Exception("it broke");
writeln("unreachable");

and compile with -w, then naturally, this won't compile because the second
statement is unreachable. That's good. However, if you do not compile with -w,
no warning is printed.

Shouldn't all warnings be printed regardless and -w simply choose to treat them
as errors? As it is, if you're foolish enough not to compile with -w, you can
easily miss stuff that's obviously wrong. I can understand the user choosing
not to treat a warning as an error, but I would expect it to still be reported,
and it's not.
