libdata-dump-perl | Perl module to help dump data structures | Mehr ...
Data::Dump provides a single function called dump that takes a list of values as its argument and produces a string as its result. The string contains Perl code that, when evaled, produces a deep copy of the original arguments. The string is formatted for easy reading. . If called in void context, the dump is printed on standard error instead of being returned. If you don't like importing a function that overrides Perl's not-so-useful builtin, then you can also import the same function as "pp" (the mnemonic for "pretty-print").
