It's been suggested a few times that C++ should allow
definition of private class member functions within
a compilation unit, without requiring that they appear

addition of private class member functions without modifying
header files. This reduces the impact on large projects
of adding private functions during implementation.
A colleague on the C++ Committee is working on a more general proposal.
It would allow partially-complete class definitions, to be completed in
an implementation file.
The proposal isn't complete yet. If we are not to invalidate current
C++ implementations, the kind of hidden features that can be added is
limited. But adding non-virtual member functions would be allowed.

Well considering the EWG was not overly keen on my proposal to allow a
way of adding to a class interface because it has an impact on overload
resolution I have my doubts that it will get enough support but I am
open to seeing the proposal.
Another possibility is to consider such extensions in the context of my
'explicit class' proposal. As this could be extended to incorporate a
rather different semantics for explicit classes such as making private
members invisible (i.e. do not participate in overload resolution) it
would work more comfortably with adding private function members in the
implementation file.
