You should write code based on best coding and design practice, not to
adhere to the whims of a particular IDE's syntax completion. Class nesting
is like function nesting in old C - it get's out of control fast. Pmpl is an
exception (and in that case the class is defined within the cpp file
anyway). For most other cases, class friendships are better.
