From 8c7ecc85f5535e9d409d51087b1119fe1e61f0cb Mon Sep 17 00:00:00 2001 From: Maxime Dénès Date: Mon, 18 Jul 2016 10:30:17 +0200 Subject: Remove the swap tactic from the prelude. It was anyway unusable due to a parsing conflict with the swap operator on goals. Was triggering a warning when compiling the prelude. --- theories/Init/Tactics.v | 6 ------ 1 file changed, 6 deletions(-) (limited to 'theories/Init') diff --git a/theories/Init/Tactics.v b/theories/Init/Tactics.v index a3eb91ec6..5d1e87ae0 100644 --- a/theories/Init/Tactics.v +++ b/theories/Init/Tactics.v @@ -55,12 +55,6 @@ Ltac contradict H := | _ => (elim H;fail) || pos H end. -(* Transforming a negative goal [ H:~A |- ~B ] into a positive one [ B |- A ]*) - -Ltac swap H := - idtac "swap is OBSOLETE: use contradict instead."; - intro; apply H; clear H. - (* To contradict an hypothesis without copying its type. *) Ltac absurd_hyp H := -- cgit v1.2.3
