Scott Morrison	35e374350c	chore: upstream norm_cast tactic (#3322) ... This is a quite substantial tactic. It also includes the infamour `NatCast` typeclass (which I've equipped with a module-doc). I wasn't at all sure where that should live, so it is currently randomly in `Lean/Elan/Tactic/NatCast.lean`: presumably if we're doing this it will go somewhere in `Init`. --------- Co-authored-by: Leonardo de Moura <leomoura@amazon.com>	2024-02-19 17:49:17 -08:00
