[heading Behavior]
* `is_transaction_safe::value` is `true` when either:
* `T` is a function type, function pointer type, function reference type, or member function pointer type where the function has a `transaction_safe` specifier
* `T` is a function object with a non-overloaded `operator()`, where the `operator()` has a `transaction_safe` specifier
* On compilers that support variable templates, `is_transaction_safe_v` is equivalent to `is_transaction_safe::value`.
