Re: SgExpression::unparse()

> Is this method defined?

No, it has not been implemented (yet). But somehow it is declared in  
libSage++.h (and it should not have been) so if you actually write a  
program that is using it, the program will compile but you will get a  
loader error. The manual was put together using info from libSage++.h  
and that is why the method is listed there. I'll put it on my "to do"  
list. Thanks for pointing it out.
