Hi, John.

> * What is your evaluation of the design?

Some questions:
1. Shouldn't there be a protected d'tor in singleton in order to
reduce the chance of mis-use (deletion via pointer to singleton)?

2. Why does instance have pointer-like (rather than reference-like)
syntax? I know that GoF use pointers, but references typically make me
feel better than pointers (or something that looks like one) which
might be 0.

3. Is a private (or protected) my_singleton destructor supported
without 'verbose "template...friend-making"'?

Not evaluated.

Not evaluated.

I'd very much like to see this kind of library in boost. This one
looks promising.

No. N/A. N/A

> * How much effort did you put into your evaluation?

A glance only due to lack of spare time. Sorry .

> * Are you knowledgeable about the problem domain?

A little: I have written some template based singleton code myself and
have read Andrei's MCPPD.

> * Do you think the library should be accepted as a Boost library?

I'd like to see the above issues addressed in some way. Apart from
that, I have no objections.

Kind regards
