Ok, here's a question though. What made you choose to

use Class::MethodMaker;

instead of

use base Class::MethodMaker;

or 

use Class::MethodMaker; 
our @ISA = qw/Class::MethodMaker/;

[download]

In other words, when should you choose inheritance rather than simple use? The barometer that I've kind of adopted is if I want my object or class to behave as a parent class, inherit. It seems that Class::MethodMaker is one of those cases.

Please forgive my continued novicity on this subject. ;)

    Because i still forget from time to time that one should always "favor aggregation over inheritance." :)

    UPDATE:
    Or am i second guessing myself again? Yes ... never mind my reply, i thought you were referring to something else. (But the concept of aggregation vs. inheritance is still important.)

    My usage simply follows what is illustrated in the POD. There is some syntactical sugar involved, so i don't read into the "useage" too literally -- think of Class::MethodMaker as magic. :)
