Clang contains a ton of warnings for code that could contain
common errors. I mean, there's nothing wrong in having
unreferenced variables but there are still compilers that warn
about this.
Also not that Clang has a static analyzer, in addition to the
warnings and errors in the compiler.
Well, that is probably the only thing I hate in Clang :) Also, I
can't imagine a single valid use case for unreferenced variables
in C/C++, so it is a bit different.
