This module 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 dump() is called in a void context, then the dump is printed on
STDERR 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(), mnemonic for "pretty-print".
