in reply to Why does ‘keys’ need a named hash?

map function is for traversing the array like a foreach loop to manipulate the data of an array or hash. Hence keys keyword will not have any effect on map function. Referencing the results of map function would ensure keys keywords identify its next statement is a hash.
