+1 for both, they would be very useful. For example vibe.d currently 
requires passing the parameter name as an argument to the UDA to work 
around the lack of support for UDAs on parameters.

Kind of related, the "deprecated" attribute would also be important to 
have for enum members [1]. I still have a bunch of enum members that 
were supposed to be removed/replaced years ago, but there is no way to 
implement a deprecation process.
