> alert me when I give map an arrayref instead of an array
^^^^^
map takes a LIST, not an ARRAY. A reference by itself is a fine
single-element list.
There is no way to not-give a list to map, since every Perl EXPRession
in list context results in a valid list. A list can have zero or any
positive number of elements.
