[Grace-core] Fwd: Query on built-in objects

[James Noble]

purely my take: 

> 1) Should ++ be defined on non-sequences? People are saying no.

no.  another question is whether we should overload "+" 
I think the consensus there is no too.

> 2) Should String.++ invoke asString? I'm not sure anyone has said

I think "no".
I'm pretty sure I never use ++ on non-sequences (in fact on non-strings)
