semantics as the similarly named tacticals in [Proofview]. The
tactical of [Proofview] are used in the definition of the
tacticals of [Tacticals.New], but they are more atomic. In
particular [Tacticals.New.tclORELSE] sees lack of progress as a
failure, whereas [Proofview.tclORELSE] doesn't. Additionally every
tactic which can catch failure ([tclOR], [tclORELSE], [tclTRY],
[tclREPEAt], etc…) are run into each goal independently (failures
and backtracks are localised to a given goal). *)
