Re: [Boost-users] null_ptr?

This is what I came up with, given your code:

static struct nullptr_t
{
    template< typename t_type >
    operator t_type* () { return 0; }
} nullptr;

One difference is that I made the nullptr object static so it could be
placed in a header without linker conflicts. Your idea is great and simple,
I like it. Thanks a lot.
