I am using Data::Dumper to save the state of a very deeply nested object to file. The nested structure contains:
A) Duplicate references to the same sub-components
B) References to functions
The problem I am having is that, in order for the duplicate references to be read correctly as duplicates, I have to set:
local $Data::Dumper::Purity = 1;
But then, when the dumper encounters the references to functions, it outputs the following message:
Encountered CODE ref, using dummy placeholder at C:/Perl/lib/Data/Dumper.pm line 190.
If I set Purity to undef, then that message does not appear, but then the duplicate references are read as separate instances.
Is there a way around this issue?
