http://d.puremagic.com/issues/show_bug.cgi?id=4978 Summary: Can't get object out of Rebindable: get is private Product: D Version: unspecified Platform: Other OS/Version: Linux Status: NEW Severity: normal Priority: P2 Component: Phobos AssignedTo: nobody puremagic.com ReportedBy: jmdavisProg gmx.com PDT --- This code import std.typecons; class T { this() immutable { } } void main() { immutable orig = new T(); auto bound = rebindable(orig); immutable backOut = bound.get; } results in this compilation error: d.d(14): Error: struct std.typecons.Rebindable!(immutable(T)).Rebindable member original is not accessible d.d(14): Error: struct std.typecons.Rebindable!(immutable(T)).Rebindable member original is not accessible As far as I can determine, get is the intended way to get the object out Rebindable!() (I certainly can't see any other way), but it doesn't work. And really, I see no point to get if it won't get you the object bound by Rebindable!(). I think that get needs to be a property which returns original rather than just an alias. The alias isn't working, and it makes really hard to use Rebindable!() when you don't want to be passing Rebindable!() around everywhere. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

http://d.puremagic.com/issues/show_bug.cgi?id=4978 PDT --- Also, the static ifs at the top are missing any kind of get, so you can't use get generically with Rebindable. Perhaps what should be done instead is to have on opCast() which casts to the original. That would work with the first static if - and obviously the struct in the else - but I'm not sure that it would work with the second one since it's const when the original could have been immutable. It is a potential concern though. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
