The code factors the setting and lookup into functions already. A 
function is an abstraction. If you're concerned about a function that 
calls find_if and then uses the result, how do you rate this one: 
https://code.woboq.org/qt5/qtbase/src/widgets/kernel/qgesturemanager.cpp.html#_ZN15QGestureManager26filterEventThroughContextsERK9QMultiMapIP7QObjectN2Qt11GestureTypeEEP6QEvent

It's using _all_ the nice abstractions!

Puts some stuff into perspective, doesn't it?
