The API is not consistent with Net::Twitter with respect to error
handling. A failed update in Net::Twitter returns false, the nature of
the error can then be ascertained with get_error, http_message or
http_code.
With Net::Twitter::OAuth the whole thing throws an exception. This
appears to be due to Net::OAuth::Simple making extensive use of 'die',
rather than returning false. A work around for Net::Twitter::OAuth
would be to wrap make_restricted_request calls in eval{} in
Net::Twitter::OAuth::UserAgent::get and
Net::Twitter::OAuth::UserAgent::post, and then attempt to parse $@ and
do something useful with the results (eg set Net::Twitter::Error).
