good point

You can definitely declare variables with Voldemort types.

e.g.
auto foo(){ struct S{} return S(); }
void bar(){ typeof(foo()) a; }

is fine.


The problem here is to do with the initialiser.

    typeof(dirEntries(path, filetype, SpanMode.depth)) files = void;

doesn't cause any problems.
