well, ctags is quite independent, extendebal and universaly used. But AFAIS it relies on regex-patterns, which is to limited for perl... but better than nothing.
By intuition I think perl-parsing needs to compile the code like flymake-mode in emacs does to find syntax errors. (hmmm...does it?)
But the "IDE-logic" per module should be supplied by the module/submodule. This way one could decide which module to use dependend on it's IDE support.
