Agreed on both counts. Personally, I'd much rather have name 
qualification and record selection use a different character than to 
remove (.) as composition. And replacing (.) with some abomination like 
`o` is unthinkable.

As for the selector character, I'm partial to # but that would clash 
with MagicHash.
