the implication relation: lhs <= rhs means lhs |- rhs

val join : t -> t -> t
val widen : prev:t -> next:t -> num_iters:int -> t
val pure : t

Pure abstract state: no side-effect on parameters and global values. The return value depends only on the value of parameters.

val impure_global : t

Impure abstract state: there may be side-effect on the parameters or global values. Or the return value may depend on the machine state, e.g. `Math.random`.

val impure_params : ModifiedParamIndices.t -> t

Impure abstract state: there may be side-effect on the parameters, but not on global values.
