Walter is not always right.

Detecting unused variables is a core feature, it belongs in the
compiler, like compile-time array bound tests and other errors
currently detected by DMD. This allows everyone to use it with
minimum work, so everyone enjoys it, and it requires less work to
be implemented because the compiler already does lot of analysis.
