https://issues.dlang.org/show_bug.cgi?id=23590 Issue ID: 23590 Summary: Deprecation: scope variable 'bar' assigned to non-scope parameter '_param_2' calling formattedWrite Product: D Version: D2 Hardware: All OS: All Status: NEW Severity: normal Priority: P1 Component: dmd Assignee: nobody puremagic.com Reporter: elpenguino+D gmail.com ``` import std.format; void foo(scope immutable(char)[][] bar) safe { static struct Result { void put(char c) safe {} } Result().formattedWrite("%s", bar); } ``` The interesting thing about this code is that the deprecation vanishes if bar is `scope immutable(ubyte)[][]` instead. Copying formattedWrite into this module seems to make the warning go away as well, so I wasn't able to reduce this example any further. --
