| Subject: | No checking of malformed YAML data |
The module accepts user-defined data in YAML format (as a way of
overriding the list of valid terms) but does not validate that the data
structure is as expected. This can cause odd errors.
(An internal version of Oxford::Calendar not released on CPAN introduced
the YAML configuration file idea, but used a differing data structure to
that now in use; this triggered the bug).
