Scoping. Convert parsed terms in core terms by finding out which identifiers are bound variables or function symbol declared in open modules.

Core.Sig_state.sig_state ->

Syntax.p_term ->
Core.Term.termscope ~typ ~mok prv expo ss env p t turns a pterm t into a term in the signature state ss and environment env (for bound variables). If expo is Public, then the term must not contain any private subterms. If ~typ is true, then t must be a type (defaults to false). No new metavariables may appear in t, but metavariables in the image of mok may be used. The function mok defaults to the function constant to None

}Representation of a rewriting rule prior to SR-checking.
val rule_of_pre_rule : pre_rule Common.Pos.loc -> Core.Term.rulerule_of_pre_rule r converts a pre-rewrite rule into a rewrite rule.
