Apparently, it is not. Do you have a reference to Walter's
change regarding `in` becoming just `const`? Because a change
like that should get reflected in the spec, otherwise we might
just continue to ignore said spec and expect our grievances to
be "gracefully" resolved later. What I mean is I'd rather
see/make the change reflected there...
Unfortunately, `in` was never implemented as `scope const`. I
think it was only when Walter started working actively on scope
that he found out that it's too late to change this -
https://github.com/dlang/dmd/pull/5898. Here are some more
references:
https://github.com/dlang/druntime/pull/1740
https://github.com/dlang/druntime/pull/1749
Going forward, I think it would be best for the language if
`in` would work as Q. Schroll described here:
http://forum.dlang.org/post/medovwjuykzpstnwb...@forum.dlang.org. This can also nicely fix the the problems with rvalues (with auto ref you may end with up to 2^N template instantiations where N is the number of parameters and 2 is because you get one by value and one by ref instance; doesn't play nice with delegates etc). See also https://github.com/dlang/dmd/pull/4717.
