This is something I was discussing with a friend recently, and we 
agreed it would be cool if there were set of operators with no 
definition until overloaded, so you could use e.g. (.) for dot 
product, (*) for cross product, (+) (or maybe [+]?) for matrix 
add, etc. instead of overloading things that already have 
specific, well-understood meaning.
