What's the best way to evar-normalize a term in Ltac2? Importantly, it should not reduce beta-redexes, should not remove vm casts nor native casts, and should not incur the overhead of typechecking the term.

Does Constr.Unsafe.check evar-normalize? eval cbv delta [id]?

Well, it seems that switching from Control.refine to Control.new_goal fixes my problem in any case
