I tried PADRE. It took long time to compile but lighter than I thought. IDE with debugger is fascinating for me. For jumping through facilities it seems the same mechanism with ctags. Suppose you are editing BBB/Bar.pm and wonder what is function aaa?

#AAA/Some.pm 
package some; sub aaa{}; 1; 
#BBB/Foo.pm
package foo; sub aaa{} ; 1;
#BBB/Bar.pm
package bar; 
 use base qw(foo);
 sub bbb{
   aaa();
  }
1;

ctags generate sorted list for aaa like this.

aaa AAA/Some.pm
aaa BBB/Bar.pm
[download]

If class hierarchy took considered, they must jump to BBB/Bar.pm's function aaa, but Padre and ctags jump to AAA/Some.pm's function aaa. I guess they use same logic and jump to first line of sorted list.

Just type g+Ctrl+] show me list of functions in ctags and vim. It is enough good to me so far. In reality, we have factory class? or something, so, much or less I have to jump with my legs.
