List:: has the connotation doing things to Perl arrays I think.
In Perl an array is a data structure which can hold a list, where a list
is understood as an ordered set of elements.
While an array is the most frequently used way of holding and
manipulating a list, it's often just a means to an end. The result of
that manipulation may or may not be -- or be represented by -- a Perl array.
In the case of List::RewriteElements, the result of the rewriting of a
particular element in a list is immediately printed to STDOUT or to a
file. It is not held in an array.
So, while List::RewriteElements can certainly be used to transform
elements of an array, a module name like 'Array::RewriteElements' would
be overly narrow.
I suspect that people will most frequently use this module to transform
data records held in a flat file, in which case we treat the individual
records within the file as elements of a list.
