Dicebot:
unused variables are job for dscanner
Unused variables/labels/arguments and unused last assignments are often flags for code problems (but the ones in the function/class you are writing now). I like how such tests are done by the GCC/Clang compilers.
signed-unsigned comparison should be an error, not warning
I don't know if Rust does this. But isn't it a little late for D? And aren't such errors going to introduce even more dangerous casts?
