From 6d92d142e5aeb867b89c4185b00be5de51b25256 Mon Sep 17 00:00:00 2001 From: Michael Dyck Date: Wed, 24 Nov 2021 15:22:11 -0500 Subject: [PATCH] Intrinsic functions: Don't repeat the parameter list in the preamble (1) The clause that defines an intrinsic function (other than an acccessor function) gives its parameter list in the clause heading. Often, the preamble re-states the parameter list. This commit (and the next) deletes those repeats. (See Issue #2576 for justification.) In this commit, we handle all the simple cases where nothing is lost by deleting the repeat. --- spec.html | 342 +++++++++++++++++++++++++++--------------------------- 1 file changed, 171 insertions(+), 171 deletions(-) diff --git a/spec.html b/spec.html index 414d8944aa1..aa700586556 100644 --- a/spec.html +++ b/spec.html @@ -28606,7 +28606,7 @@
