I agree that #5 seems like the best solution. The problem is caused by the double meaning of ::. All of the other solutions feel like bandaids. Of course, the problem then is finding a symbol that is not already used. I don't think reusing -> is any wiser than reusing ::. # would be great if it wasn't already in use, but that sort of change is really not appropriate for 5.3. What other symbols are available or could be created?
