Comment (by eclev91):

 I'm actually inclined to agree, but think it might be worth reviewing as
 an enhancement. If `$capabilities` is passed a numerically-keyed array (or
 "not associative", however one ultimately decides to interpret that), that
 it be assumed each cap should be assigned as "true".

 Thoughts?

 Semi-related, what's the use case for explicitly saying someone doesn't a
 capability (`"my_cap" => false`)?
