@BLT, still very nice. Makes any answer using apply with an anonymous function that bit shorter.

@JarkoDubbeldam it tends to get confused for more complex functions but for simple ones, it infers the arguments so you don't have to declare them (or write function). If only the package name were shorter...

@Giuseppe Not sure if TRUE counts as falsey though :/

or you could also say any(unlist(x)-2) which returns a consistent TRUE if there is a non-2 value in the flattened array and a consistent FALSE if all the values are 2...

this is the same length as all(unlist(x)==2) as well.

pryr::f(!any(unlist(x)-2)) saves a couple of bytes.
