val var_to_simple_var : ?⁠prefix:string -> ctx -> t Logtk.HVar.t -> Logtk.TypedSTerm.t Logtk.Var.t
exception Error of Logtk.TypedSTerm.t
val of_simple_term_exn : ctx -> Logtk.TypedSTerm.t -> t
raises Invalid_argument

if conversion is impossible

val to_simple_term : ?⁠env:Logtk.TypedSTerm.t Logtk.Var.t Logtk.DBEnv.t -> ctx -> t -> Logtk.TypedSTerm.t
