Hello, I'm trying to write some test code for the subroutine ScanDeps however, I'm seeing some odd behaviour that I can't explain. A cut-down version of my test code looks like this:

I have some trouble understanding what your actual problem may be: indeed you did good to prepare a cut-down version of you code, but you should go as far as making that into a minimal but complete example exhibiting the problem. You should specify what output you expect and what you get instead.

use Data::Dump qw(dump);
print dump $rv;

Data::Dumper exports Dumper() and AFAICT knows no dump():

C:\temp>perl -MData::Dumper=dump -e ""
"dump" is not exported by the Data::Dumper module
Can't continue after import errors at -e line 0
BEGIN failed--compilation aborted.

However, adding these lines somehow caused my test to start working!

However, you failed to explain how it was failing to work before you added them.

$rv without the dump lines:
[snip]
$rv with the dump lines:
[snip]

Very hard to believe...

Update: misread Data::Dumper for Data::Dump, thanks to rhesa for pointing out.
