The formatter turns a Syntax
tree into a Format
object, inserting both mandatory whitespace (to separate adjacent
tokens) as well as "pretty" optional whitespace.
The basic approach works much like the parenthesizer: A right-to-left traversal over the syntax tree, driven by parser-specific handlers registered via attributes. The traversal is right-to-left so that when emitting a token, we already know the text following it and can decide whether or not whitespace between the two is necessary.
