I'd just point out that if one wanted to make the n-triples design look 
compatible with n3's path syntax from the point of view of user 
understanding, that in the path syntax, traversal (the derivation of 
new bnodes by specifying a forward or reverse property) goes from left 
to right.


would be the way around, where ^^ could be informally read as something 
like "interpreted as".

I think as a syntax its more common by analogy with (eg) units to put 
the units at the end.

While ^^ is not a real traversal operator (operating at the syntax 
level in the parser and never being visible in the triples produced),  
it doens't  *have* to be compatible with path syntx, and of course 
n-triples nd n3 don't *have* to be subset and superset.  It's just a 
question of trying to minimize the messing with the user's brain, 
reducing learning etc.

I think the examples I had in my last message were the wrong way around.


PS: Language design is a question of balancing different metaphors to 
make it more natural. I have listed some of the choices in the path 
syntax in http://www.w3.org/DesignIssues/N3Alternatives
