 # Inference
 
 The type inference engine is pretty smart. It does more than looking at the
-type of the
-[r-value][rvalue]

 during an initialization. It also looks at how the variable is used afterwards 
 to infer its type. Here's an advanced example of type inference:

 No type annotation of variables was needed, the compiler is happy and so is the
