How this PR fixes the problem?

This PR disables use_bool_op when Objective C is detected.

I would appreciate some help to to update this PR to a more robust implementation though.
I've written a small POC that adds an additional check to has_bool_op that fails when the given type is convertible to a block-pointer: https://godbolt.org/z/GhM63xYnd

The implementation seen above is not implemented in this PR as I've used std::function to deduce the return and parameter types. I tried to do this with the function_trait found in the library, however, it does not seem to cover lambdas ootb, so I figured I might ask here first before modifying function_trait.
