I hope it's not too late to throw in my 2 cents on this subject...

I highly, highly, highly recommend NOT using syntactic indicators
that will control inheritance. Special naming conventions like 
underscores before or after do not harm anything; but using 
what could be construed as operators will play havoc with the
existing expression parser. Don't extend operator syntax into
object names; it will limit what operators we will be able to use
in anything that has to deal with those names.

Like I said, using underscores doesn't extend or change the rules
for parsing names, so that's OK, but almost anything else will
have unintended effects that will be negative.
