[C++-SIG] setattr and CXX-4.2

[Phil Austin]

I'm curious about the asymmetry between getattr and setattr in
CXX_Extensions.h: I don't see the setattr equivalent to

	virtual Object getattr_methods( const char *_name )

Is this because it hasn't been implemented or because it isn't needed?
I'm asking mainly to see whether I understand what's going on with
CXX, rather than from any immediate need to get/set member data.

Thanks, Phil
