`&*handle`, if handle is null, is undefined-behavior 

This patch fixes an undefined behavior: when one want to convert a
handle to a point, we used `&*handle` a lot. But dereferencing the
default-constructed (null) handle, is undefined-behavior.

The patch calls `operator->` of the handle class, instead.
