Functions

contains_exterior_struct_lit	Expressions that syntactically contain an "exterior" struct literal i.e., not surrounded by any parens or other delimiters, e.g., X { y: 1 }, X { y: 1 }.method(), foo == X { y: 1 } and X { y: 1 } == foo all do, but (X { y: 1 }) == foo does not.
needs_par_as_let_scrutinee	Suppose we have let _ = e and the order of e. Is the order such that e in let _ = e needs parenthesis when it is on the RHS?
prec_let_scrutinee_needs_par	In let p = e, operators with precedence <= this one requires parenthesis in e.
