'map' returns a *list*. This list can be coerced into an array or into a
hash (if it has an even number of elements). It's the same as literal
list assigment; you can both do:
@array = (1,2,3,4);
%hash = (1,2,3,4);
Also
@array = (1,2,3);
But not (gives an 'Odd number of elements in hash assignment' error):
%hash = (1,2,3);
But remember: map never returns a reference! See
perldoc -f map
for the details.
