#The reason for this is that Enumerable merely wraps the
#object’s #each method. In the case of String, #each by
#default splits the string at each line (as determined
#by the record separator constant $/).

is it possible to pass a param for collect/map to signal the separator
(akin to split)? eg

“12345”.collect(//) { |x| x.to_i}
==> [1, 2, 3, 4, 5]

and noting that

“12345”.split(//).collect{|x| x.to_i}
=> [1, 2, 3, 4, 5]
