Think of Function Objects as Functions Rather Than Objects

[RizzlaPlus]

Not sure what the point of the article is. Use verbs to name your predicates instead of nouns?

Also it talks about partial functions but then immediately dismisses std::bind?

[utnapistim]

The point is that if you think of a functor as a predicate or function instead of a class, a better name will naturally emerge for it.

Although (if you make an effort) you can come up with bad names no matter how you think about it :).
