Hello everyone
Is there a reason why boost::bind does not overload the logical operators || and &&? They definitively would come in more handy to build up complicated logical expressions than using the std::logical_and and std::logical_or function objects.
My guess is that since boost::bind could not replicate the behavior of && and ||, the authors decided not to provide them.
The built in && will not evaluate the second argument if the first is false. Similarly, the built in || will not evalulate the second argument if the first is true.
You are absolutely right. I couldn't think of an elegant way to replicate the behavior of the built-in logical operators at the time I added support for the rest. This thread did spark my interest though and I was able to add && and || to the trunk, complete with the proper short-circuit semantics.
