From 3f81d84c9ff84f057628de58ebd009112f9d46f9 Mon Sep 17 00:00:00 2001 From: Iain Buclaw Date: Sun, 19 Apr 2020 18:02:17 +0200 Subject: libphobos: Merge upstream phobos bf0d0a37c std.array.Appender and RefAppender: use .opSlice() instead of data() Previously, Appender.data() was used to extract a slice of the Appender's array. Now use the [] slice operator instead. The same goes for RefAppender.
