"Some people say that initializing to null adds a hint to the reader that
it's an access. That seems (a) kind of redundant, since I should always use the
type of the object for such information, and (b) kind of dangerous, since
initial values for access types aren't always "null". If I use the keyword
to look for access values, I'll miss some."

I don't think that's the point at all, the point is to make it explicit
to the reader that the initial value of null is important from a semantic
point of view, rather than just an accident of the definition.
