Re: [boost] bind in deduced context

add( BOOST_PARAM_TEST_CASE( bind( &test_mask, _1, 0x80 ), parameters_list.begin(), parameters_list.end() ) ) );

I get the following error:

error C2661: 'boost::unit_test_framework::create_test_case' : no overloaded function takes 4 arguments

It all caused by the fact that following fails:

void moo( int , int ) { }

template<typename T> void foo( boost::function1<void,T> const& f ) {

}

...

foo( bind( &moo, _1, 1 ) );

This is not bind-specific. Try, for example: void test(int) { } int main() { foo( test ); } T in function1<void, T> can only be deduced from function1<void, U>. No other function object will work.
