          Issue ID: 21803
           Summary: "@nogc:" incorrectly propagates into function blocks
           Product: D
           Version: D2
          Hardware: x86_64
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P1
         Component: dmd
          Assignee: nobody@puremagic.com
          Reporter: eyal@weka.io

This compiles successfully:

  struct S {
      @nogc
      void f() {
          scope dlg = { new int; };
      }
  }

Whereas this doesn't, because it complains the "new" violates @nogc.

  struct T {
      @nogc:
      void f() {
          scope dlg = { new int; };
      }
  }
