Thanks for finding that. I'm surprised the bug had survived that
long. I guess very few people use GIOP 1.1 -- most things are either
1.0 or 1.2. I've checked in the fix.

I will... ;-)

I definitely don't want to go into that religious war.

The cdrStream insertion operators are intentionally different from the
iostream (and similar) operators to prevent confusion between the two
-- they behave differently, so they are made to look different. Using
>>= also avoids the good old confusion about whether cout << 1 << 2
prints 12 or 4. Regardless as to whether anyone thinks the current
scheme is sensible or not, I'm sure you'd agree that it's not sensible
to consider changing them all now.
