def Lean.MVarId.assert (mvarId : Lean.MVarId) (name : Lean.Name) (type : Lean.Expr) (val : Lean.Expr) : Lean.MetaM Lean.MVarId

Convert the given goal Ctx |- target into Ctx |- type -> target. It assumes val has type type

def Lean.MVarId.note (g : Lean.MVarId) (h : Lean.Name) (v : Lean.Expr) (t? : optParam (Option Lean.Expr) none) : Lean.MetaM (Lean.FVarId × Lean.MVarId)

Add the hypothesis h : t, given v : t, and return the new FVarId.

def Lean.MVarId.define (mvarId : Lean.MVarId) (name : Lean.Name) (type : Lean.Expr) (val : Lean.Expr) : Lean.MetaM Lean.MVarId

Convert the given goal Ctx |- target into Ctx |- let name : type := val; target. It assumes val has type type

def Lean.MVarId.assertExt (mvarId : Lean.MVarId) (name : Lean.Name) (type : Lean.Expr) (val : Lean.Expr) (hName : optParam Lean.Name `h) : Lean.MetaM Lean.MVarId

Convert the given goal Ctx |- target into Ctx |- (hName : type) -> hName = val -> target. It assumes val has type type

def Lean.MVarId.assertAfter (mvarId : Lean.MVarId) (fvarId : Lean.FVarId) (userName : Lean.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.

def Lean.MVarId.assertHypotheses (mvarId : Lean.MVarId) (hs : Array Lean.Meta.Hypothesis) : Lean.MetaM (Array Lean.FVarId × Lean.MVarId)

Convert the given goal Ctx |- target into Ctx, (hs[0].userName : hs[0].type) ... |-target. It assumes hs[i].val has type hs[i].type.

def Lean.MVarId.replace (g : Lean.MVarId) (hyp : Lean.FVarId) (proof : Lean.Expr) (typeNew : optParam (Option Lean.Expr) none) : Lean.MetaM Lean.Meta.AssertAfterResult

Replace hypothesis hyp in goal g with proof : typeNew. The new hypothesis is given the same user name as the original, it attempts to avoid reordering hypotheses, and the original is cleared if possible.
