Short answer to this is that those types of cases could (and perhaps
should) be covered by property getter/setters.  We *could* bake it
into the syntax, and it would certainly make the syntax for PHP
scripts look cleaner, but as a first step focusing on constant scalars
only allows us to take a step forward and reevaluate to see where we
are after a version.
