As I understand it, an 'interface' is, by definition, never gonna have an
actualy object instantiated.
Thus, there can never *BE* an object for which private/public/protected
have any meaning.
You can only use the private/public/protected on the 'class' definitions.
Even if you *KNOW* that all class definitions *should* for this to be
'public' it just doesn't make sense from the strictly technical
stand-point of what an 'interface' is to declare it there.
Maybe somewhere over on php-dev you could make the case for the PHP Dev
Team to implement something good/interesting when public/protected/private
is used there, but currently it's semanticly undefined to have it there,
so it can't be there.
Disclaimer: I could easily be 100% wrong in this entire post. :-)
