98e6cafdc8 [stdlib] Adding a deprecated version of flatMap to warn misuses. (#7823) 
Due to implicit promotion to optional it is possible to call flatMap
with a closure, that does not return an optional. This way the code
works, but is unnecessary inefficient. Such uses of flatMap can and
should be replaced with map.
