Hi Peter,

My concerns about the sample code not being quite right was actually not
this reinterpret_casts (though, I do agree that they are a bit fishy --
please see next paragraph). I was worried about temporary lambda expressions
and function objects being carried around to other scopes. I can not quite
see if this valid or not..

As a side discussion, well it is kind of off topic but now that you brought
it up, there was a case where I couldn't get away with using member pointers
and needed this pointer algebra. I'd appreciate any idea on this. The
problem is simple. Take this struct,

struct A { double a[3]; }

For, this I needed to callback, say, a[2].  A callback facility designed
with member pointers wouldn't be able to handle this case.  Right?
