https://issues.dlang.org/show_bug.cgi?id=24415 Issue ID: 24415 Summary: only doesn't work with elements that have a copy constructor Product: D Version: D2 Hardware: x86_64 OS: All Status: NEW Severity: normal Priority: P1 Component: phobos Assignee: nobody puremagic.com Reporter: issues.dlang jmdavisProg.com This code --- void main() { import std.range; auto a = only(S.init); auto b = a; } struct S { this(ref return scope inout(S) rhs) scope safe inout pure nothrow { } } --- results in the error --- q.d(6): Error: no property `__ctor` for `b` of type `std.range.OnlyResult!(S)` /usr/local/include/dmd/std/range/package.d(10333): struct `OnlyResult` defined here --- The error seems to stem from the fact that OnlyResult declares a copy constructor but then makes it private for some reason. --
