Helper functions for using the simplifier.

[TODO] Reunification of mkSimpContext' with core.

def Lean.Meta.Simp.mkEqSymm (e : Expr) (r : Result) : MetaM Result

Flip the proof in a Simp.Result.

def Lean.Meta.Simp.mkCast (r : Result) (e : Expr) : MetaM Expr

Construct the Expr cast h e, from a Simp.Result with proof h.

abbrev Lean.Elab.Tactic.mkDischargeWrapper (optDischargeSyntax : Syntax) : TacticM Simp.DischargeWrapper

Construct a Simp.DischargeWrapper from the Syntax for a simp discharger.

def Lean.Meta.Simp.mkSimpContext' (simpTheorems : SimpTheorems) (stx : Syntax) (eraseLocal : Bool) (kind : Elab.Tactic.SimpKind := Elab.Tactic.SimpKind.simp) (ctx ignoreStarArg : Bool := false) : Elab.Tactic.TacticM Elab.Tactic.MkSimpContextResult

If ctx == false, the config argument is assumed to have type Meta.Simp.Config, and Meta.Simp.ConfigCtx otherwise. If ctx == false, the discharge option must be none
