What is the type of "null" in the D typesystem?

writeln(typeid(typeof(null))) yields void* :)
Are you suggesting that the type of "null" is
opaque or merely saying what the D compiler says
without an opinion?
There was a smile there, no? Alright, alright, joking mood off.
Personally, I'd suggest that null has no 'type' by itself, but adapts to
whatever type is applicable in certain use case. It may be viewed as if
D had several different 'nulls' for every existing and user-defined
reference type.
