AFAICT it already does that if it manages to infer the type (but adds
"auto" as a storage class), e.g.

		auto outBuffer = new char[dwSize+1];

shows "auto char[]" in the tool tip for outBuffer. It's known to fail
for some complex cases, though, e.g. with the return type of multiple
function overloads.
