Devel::TraceUse - show the modules your program loads, recursively

An apparently simple program may load a lot of modules. That's useful, but sometimes you may wonder exactly which part of your program loads which module.
Devel::TraceUse can analyze a program to see which part used which module.
I recommend using it from the command line:
$ B<perl -d:TraceUse your_program.pl>
This will display a tree of the modules ultimately used to run your program. (It also runs your program with only a little startup cost all the way through to the end.)
Modules used from your_program.pl:
Test::MockObject::Extends, line 6 (0.000514)
Test::MockObject, line 6 (0.000408)
Scalar::Util, line 9 (0.000521)
List::Util, line 12 (0.000393)
XSLoader, line 24 (0.000396)
UNIVERSAL::isa, line 10 (0.000436)
UNIVERSAL, line 8 (0.000247)
UNIVERSAL::can, line 11 (0.000428)
Test::Builder, line 13 (0.000413)
Devel::Peek, line 8 (0.000693)
