I usually use Data::Dumper to browse and debug my scripts with complex data structures. This is getting painful when it grows to > 5000 lines of Data::Dumper output. What would be nice is some module that can display that data structure in a GUI collapsable tree, ala a directory tree browser.

DDD has a great data displaying and browsing, but its perl support is slow and buggy.

A check on CPAN doesn't seem turn up anything. I would write one if I can't find one soon enough but the code would not be maintainable.

Preferable usage would be replacing

use Data::Dumper;
print Dumper $complex;

to

use Data::TkBrowser;
Data::TkBrowser::browse $complex;
