Is there a nice clean perl way to test to see if only one key of a hash has data?
%some_hash = ( key1 => 1, key2 => 2 ); should fail the test %some_hash = ( key2 => 2 ); should pass the test %some_hash = ( key1 => 1 ); should pass the test Thank you -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] <http://learn.perl.org/> <http://learn.perl.org/first-response>
