AllSatisfy:     " for all x, ... is true "
AnySatisfy:     " there exists x such that ... is true "

NotAllSatisfy:  " there exists x such that ... is false "
NotAnySatisfy:  " for all x, ... is false "

NoneSatisfy: " for all x, ... is false "

The first three, and then either or both
of the last two, above, would satisfy me.

Because
        AllSatisfy: [:x| x _endsWith: 'fy']
and
        NoneSatisfy: [:x| x _endsWith: 'fies']

is easier to remember than

        NotAllSatisfy: [:x| x _endsWith: 'fy']
and
        AnySatisfy: [:x| x _endsWith: 'fies'].
are.
