On Perl v5.10.1 I get the following errors:

Type of arg 1 to keys must be hash (not hash element) at ./duplicityBackup line 541, near "}) "
Type of arg 1 to each must be hash (not array slice) at ./duplicityBackup line 642, near "])"
Type of arg 1 to each must be hash (not array slice) at ./duplicityBackup line 711, near "])"

./duplicityBackup has too many errors.

But not on version 5.14.2.

According to perldoc:

Starting with Perl 5.14, keys can take a scalar EXPR, which must contain a reference to an unblessed hash or array. The argument will be dereferenced automatically. This aspect of keys is considered highly experimental. The exact behaviour may change in a future version of Perl.
