Subject: [boost] [type_erasure]

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
