Great to hear, that is actually my primary goal with boost reflect, minimize extra typing.

vtable.hpp line 47 should never actually be instantiated unless you attempt to use it with
a type that has not had the BOOST_REFLECT_ANY() macro specified for it. That said, the
correct fix is vtable<InterfaceType,InterfaceDelegate>. I had changed the template parameter
to be more descriptive for documentation purposes and missed that.

You are correct, documentation error. It has been updated.

Also correct. I have updated the example to reflect that and added a new helper to the example that
should simplify things. xml_printer::make( t ) will deduce the type for you, useful if t is complex.

Thanks for all of your input, changes have been checked into git and documentation updated.

I have only tested on Mac OS X with gcc 4.5 and 4.2.1, limited testing on Windows. I suspect that Boost.Context will need a small
CMake change to link the proper asm. On Windows you have to use the nmake build because a cmake
bug prevents it from compiling the Boost.Context asm with the VS generators.

More documentation is coming.
