Is Clone() still used by ANTLR C# in 2.7.2?
I'm away from the ANTLR C# code presently...

Yes. The semantics of node cloning in ANTLR excludes that feature. 
Pls see previous related discussion on the list. 

IIRC, the copy-by-Clone() mechanism has now been replaced with a copy-
via-reflection mechanism. The Clone()-related code will be deprecated 
and excised in due course unless someone *needs* it. 

Cheers,

Micheal
