A12 - Protected Attributes and Methods

[Joe Gottman]

   Apocalypse 12 was very clear about the difference between private and
public class members, but it didn't say anything about protected ones?  How
can you define a protected member?   Do you have to do the following?
    has $.foo is protected;
    method bar() is protected;

   Maybe we could have another secondary sigil to mark a protected method or
attribute.  I'd suggest the semicolon, but I'm afraid it would cause havoc
with the parser.
