  I remember that I've read many good books that use to give a basic exampl=
e, but before showing that example they use to say that "This is not the ri=
ght way to do it, and you will learn later why", or told that there are muc=
h better ways, but they still shown that basic example.

  For example, when I have started learning Perl for creating CGI applicati=
ons, I didn't start directly by using "use CGI" but by checking if the requ=
est was a GET or POST method, and if it was a GET to parse manually the que=
ry string, and if it was a POST method to parse the STDIN for getting the v=
ariables.

  Of course I have learned immediately that it is much more simple to use t=
he CGI module, but that way of learning helped me much to understand better=
 how the CGI module works, and how it gets those variables.

  Now I can see many PHP users that don't understand what's really a GET me=
thod or a POST method, and they think that a POST method is much secure tha=
n a GET one and so on, because the way of getting the variables from the us=
ers is built in PHP, so they don't need to care.

  Using Catalyst with an ORM means using a higher level of programming, and=
 this makes the users understand harder the low level things, in order to b=
e able to use other methods, for example accessing a database from Catalyst=
 directly.
