opaque Lean.Elab.cleanup.letToHave : Lean.Option Bool

structure Lean.Elab.PreDefinition : Type

A (potentially recursive) definition. The elaborator converts it into Kernel definitions using many different strategies.

• ref : Syntax
• kind : DefKind
• levelParams : List Name
• modifiers : Modifiers
• declName : Name
• type : Expr
• value : Expr
• termination : TerminationHints
