Module S.Kind

type t
val compare : t -> t -> int
val matches : caller:t -> callee:t -> bool

Return true if the caller element kind matches the callee element kind. Used during trace expansion; we will only consider expanding the trace from caller into callee if this evaluates to true. This can normally just be equal, but something fuzzier may be required if t is a type that contains identifiers from the caller/callee
