Hi,
I have finished the rewrite of Devel::TraceUse. I've just
sent you a pull request on github. The repository is at
http://github.com/book/Devel-TraceUse
Just to show the differences, I've included the output on a simple example.
Current Devel::TraceUse:
$ perl -d:TraceUse -MLWP::UserAgent -e1
Modules used from -e:

Some notes on the new Devel::TraceUse:
- it doesn't load any module, to avoid intering with the traced program
- it shows module loading order, which makes it easier to spot
modules loaded at runtime
- it shows if the module was loaded from within an eval ""
- it uses information from the debugger to correctly attach
modules loaded with eval ""
- it indicates if a module couldn't be loaded
- it show the loading package if different from the loading file
Hope you like it,
