Hi,
I am trying to use Boost.TypeErasure library with a 'concept' that provides
contextual conversion to *bool*. That is, I want to type-erase types that
provide the following operations for some invented object *o*:

*  if (o) {}*

*  if (!o) {}*
*  bool (o); *

I cannot find a predefined concept for that, nor can I use
BOOST_TYPE_ERASURE_MEMBER or BOOST_TYPE_ERASURE_FREE, because that will not
work for built in types. Is there any convenience tool that enables
specifying such concept?

Regards,
&rzej
