def Lean.MVarId.assertAfter (mvarId : Lean.MVarId) (fvarId : Lean.FVarId) (userName : Lake.Name) (type : Lean.Expr) (val : Lean.Expr) : Lean.MetaM Lean.Meta.AssertAfterResult

Convert the given goal Ctx |- target into a goal containing (userName : type) after the local declaration with if fvarId. It assumes val has type type, and that type is well-formed after fvarId. Note that val does not need to be well-formed after fvarId. That is, it may contain variables that are defined after fvarId.
