I'm only concerned with
This function calls a function object by passing an object of the matching
The contents of this object usually do not matter -- and in case they do,
the programmer can write a default constructor to initialize this object.
So there is no need in boost::mpl::for_each to call value_initialized.
Another solution would be to pass a zero pointer to an object of this type.
Anyway -- this argument is only used to select the correct template method
of the function object passed.
