Hej all,

For the past 5 weeks I've been writing a Perl module and its getting big, REALLY big - like 3000 lines so far.

One things that comes to mind is that there are maybe 100 object variables you can access from the module, but internally, every function has its own "my" declared variables and constants for use within that function.

Many of these are arrays and hashes that store data that is being sorted or maniputlatied before being pushed into object variables.

I've reused variable names in different functions and I'm wondering, do variable names get reused? I mean, if I have a function A with variable my $name = "Jed"; and then in function B I declare my $name = "Ted"; then do two variables called $name exist in memory?

Guestimating, I said that my 3000 line module probably holds maybe 128k of data in local variables and produces 512K - 2048k in object variables and I'm just a little concerned about speed and memory usage as this is called via CGI which will spawn a new instance.

Anyone got any tips or info on ways to make clean, efficient modules?

- Jed
