I agree with you, that its nice to know at compile time, but perl isn't like tha...
Yes, some one else is going to chime in and say "Perl OO isn't like that", and I'll say "why shouldn't it be?". Hint: that's a rhetorical question.
Its not so much that Perl is not like that, its that the more "dynamic" OO languages are not like that. Smalltalk, Python, etc. etc. most of them don't have a concept of public, protected and private either. It's really an idea that is much more acceptable in a more "static" OO language where such "restrictions" are the norm. It's a trade-off really.
Personally, I am waiting to see how they solve issues like this in the Perl 6 object model. It should be very interesting.
