This module started out as C<Data::Transform::Named>, a named
wrapper (like C<Sub::Chain::Named>) around L<Data::Transform> (and
specifically L<Data::Transform::Map>).
As the module was nearly finished I realized I was using very
little of L<Data::Transform> (and its documentation suggested that I
probably wouldn't want to use the only part that I I<was> using). I
also found that the output was not always what I expected. I decided
that it seemed reasonable according to the likely purpose of
L<Data::Transform>, and this module simply needed to be different.
So I attempted to think more abstractly and realized that the
essence of the module was not tied to data transformation, but
merely the succession of simple subroutine calls.
I then found and considered L<Sub::Pipeline> but needed to be able
to use the same named subroutine with different arguments in a
single chain, so it seemed easier to me to stick with the code I had
written and just rename it and abstract it a bit further.
I also looked into L<Rule::Engine> which was beginning development
at the time I was searching. However, like L<Data::Transform>, it
seemed more complex than what I needed. When I saw that
L<Rule::Engine> was using [the very excellent] L<Moose> I decided to
pass since I was doing work on a number of very old machines with
old distros and old perls and constrained resources. Again, it just
seemed to be much more than what I was looking for.
