I have been looking at some rudimentary code analysis of local Perl code. I had been getting by on the cheap by finding the beginning & end of subroutines by counting braces followed by looking for calls of the subroutines found within the same file.

The problem becomes magnitudes harder when I have started looking at looking at multiple modules at the same time. If modules A & B both define get_width(), the following becomes impossible to resolve: 

sub is_too_large {
    my ($a, $b) = @_;
    return $a->get_width() > $b->get_width();
}

Do any of you smart people have any thoughts on how I can approach this problem? If there are CPAN modules which can help, I haven't found them yet.

Any insights offered would certainly be appreciated.
