My first thought as I read your question is, "Why?" I have lost touch with
C++ and the myriad directions it has sprawled into, but I simply don't see
why you would ever have any reason to implement this type of behavior. Objective-C
is weakly typed and late bound, so I don't understand what you would achieve
by doing this. The runtime engine just doesn't care what ISA is, it only cares
if the object responds to a message or not, and even if it doesn't, it doesn'
t really hurt much if you send it that message.
C++ is a confining and restrictive language, which is why it has incorporated
every good idea (or seemingly good idea) that has come along. While I do think
there are a few areas where Objective-C could use some tweaking (e.g. something
like Java packages so that we didn't all need to funk up our class names with
preliminary initials), but overall it's a fine example of simpler is better.
C++ has many things Objective-C does, but very few that Objective-C needs.
Trying to compare C++'s RTTI to Objective-C's introspection is almost ridiculous.
So, I'm sure there is a way to implement what you suggest without changing
the runtime engine, but I can't imagine that anyone would.
But please feel free to elucidate if you think there is a compelling reason
for adding this...
