Rust Pretty printing closures

// how pretty printer formats closures (I think; I'm unable to build from incoming right now to check)

// how they would be written by a person (in my opinion)

/* What this means:
 * closures should not be wrapped inside a box of their own - the argument list 
 * and opening bracket should be part of the head, and the contents of the closure
 * should be a block.
