           Summary: allow cast(ref T)lvalue for casting lvalues
           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

This is a really tired pattern:
  *cast(T*)&lvalue

We should allow:
  cast(ref T)lvalue

This is just so much clearer.
