does perl support inheritance?

Sort of. Take a look at perltoot and seek out the explaintion of what

package myModule; 

use vars qw/ @ISA /;

@ISA = qw/ otherModule /;  # This is also an "otherModule"
[download]

sort of thing does for you. There are limitations and you need to be sure to understand those limitations to minimize your frustrations.

You can also do things like:

package Foo;

use base qw/ Bar Baz / ; 
  |
[download]

which is taken from the base man page. This also is a good read before proceeding further.
