why does perl allow mutually "use" relationship between modules
- by Haiyuan Zhang
let's say there two modules mutualy use each othe as:
package a;
use b;
sub p {}
1;
package b;
use a;
1;
I think symatically it's wrong to wrote code like the above code, cus the two modules will endlessly copy each other's code to themselves...but I can successfully run the following code, which makes me very surprised. so could any of you explain all of this to me?
#! /usr/bin/perl
use a;
a->p();
