           Summary: Add standard @nodiscard attribute for functions
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P1
         Component: dmd
          Assignee: nobody at puremagic.com
          Reporter: turkeyman at gmail.com

Can we please have a standard @nodiscard attribute that all implementations
agree on?
Do want compile errors when functions discard the result form @nodiscard
functions.
It can help reduce bugs in some cases, and it's a very nice self-documenting
feature which makes the API intent a little clearer.
