I think I'm gaining some understanding...
Your second code example works because the anonymous subs are within the same lexical scope; therefore, there is no need to store the variables they work with separately (in $self, like I did). Correct? I like that.
The last block of code looks similar to mine, one of the differences being that you only call $self->filter($r) within the loop. Wouldn't the code within filter() be same difference to what I'm doing? That is, I still need an increment and a hashing, so filer() would contain ++$self->{count}; and so forth?
I believe I'm lost somewhere in between "
This is only natural inside a single object, however your callbacks are all external to your object, so that doesn't make a bunch of sense to me." and "
As in your filter object. Thus it makes perfect sense to modify object variables inside object methods, so you can do whatever you want with it." The latter statement says to me: "There are no closures (external thingies) involved, therefore everything happens within your methods," which makes me think "Well then, how do i keep this dynamic? Each filtering process is going to be 80% common, but there is some variation."
Thanks for your time.
P.S. I am reading through perltoot, perlobj, a few tutorials on this site, and the llama.
