ruby facets map is to every as find is to?

Question

the every method is defined as

...
def every
  per(:map)
end
...

does facets define a method for

...
    # name not relevant
def find_where
  per(:find) # or :detect
end
...

I've checked the documentation, most likely I'm just missing it

Answer 1

actually it sort of is in their docs Using fluid notation

([1,2,3].per.map + 3) or in my case ([1,2,3].per.find == 3)
