[Boost-users] [bind, function] bind a cast

Hi

Is there any easy way to bind an explicit type conversion ?

For example, I want to supress compiler warning here with static_cast:

#include <boost/bind.hpp>
#include <boost/function.hpp>

int main(void)
{
  boost::function<long (void)> foo;
  boost::function<short (void)> bar;
  bar = foo; // compiler warning.
  bar = boost::bind<short>(foo); // the same warning
  //bar = boost::bind(static_cast<short>, foo); // does not compile
  return 0;
}

If not, I think it might be added. Casts are useful sometimes not only to 
avoid warning, but also to get code compiled.
