when you want to make a function that acts as getter/setter for
delegate callback, for example.

  private void delegate () cb;
  @property auto myCB () { return cb; }
  @property void myCB (void delegate () newcb) {
    /* some checks */
    cb = newcb;
  }

this will work as expected when property enforcement will be fixed --
i.e. you will be able to omit '()' for calling delegate.

alas, this is another thing that is "cosmetic", so PR with property
enforcement will rot on github forever.
