Re: [boost] Template Metaprogramming experiments w/smart pointers

A third experimental program and associated header has been added to 
http://www.egroups.com/files/boost/TMPX/

Scoped or shared ownership features were added in experiment 3 to make the 
experiment more realistic.  A separate header was added for the same 
reason.

The changes (compared to experiment 2) to add these features were trivial 
and had virtually no impact on code unrelated to the change itself.

Experiment3.hpp now has the bulk of the functionality found in 
boost/smart_ptr.hpp, plus the ability to specify no delete or supply a user 
delete function.

Because template metaprogramming encouraged factorization, experiment3.hpp 
may actually be easier to read and understand that boost/smart_ptr.hpp.  At 
least if you understand the idioms.

In addition to meta_assert, the other need which turned up is the ability 
to mix in non-member functions.  Maybe C&E have a way to do that, I'll look 
for it.

Documentation is going to be a challenge; I expect it may have to be 
generated on demand too.

Comments?
