          Issue ID: 12622
           Summary: Purity, @safe not checked for pointers to functions
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: major
          Priority: P1
         Component: DMD
          Assignee: nobody@puremagic.com
          Reporter: bugzilla@digitalmars.com

Given:

  void bar16();

  @safe void foo16() {
    auto fp = &bar16;
    (*fp)();          // should give error

    bar16();          // correctly gives error
  }

Replacing @safe with purity or @nogc, and no error is given. It does work for nothrow.
