side tables | because the AST and HIR are immutable once created, we often carry extra information about them in the form of hashtables, indexed by the id of a particular node. side tables | because the AST and HIR are immutable once created, we often carry extra information about them in the form of hashtables, indexed by the id of a particular node.

soundness | soundness is a technical term in type theory. Roughly, if a type system is sound, then if a program type-checks, it is type-safe; i.e. I can never (in safe rust) force a value into a variable of the wrong type. (see "completeness"). soundness | soundness is a technical term in type theory.

span | a location in the user's source code, used for error reporting primarily. These are like a file-name/line-number/column tuple on steroids: they carry a start/end point, and also track macro expansions and compiler desugaring. All while being packed into a few bytes (really, it's an index into a table). See the Span datatype for more. span | a location in the user's source code, used for error reporting primarily.
