           Summary: Const values in tuples
           Product: D
           Version: D2
          Platform: x86
        OS/Version: Windows
            Status: NEW
          Keywords: rejects-valid
          Severity: major
          Priority: P2
         Component: DMD
        AssignedTo: nobody puremagic.com
        ReportedBy: bearophile_hugs eml.cc



I think the need to put const values inside tuples is very common:


import std.typecons;
void main() {
    const int x = 1;
    auto t1 = tuple(x);
    alias Tuple!(const(int)) T;
    auto t2 = T(1);
}


In DMD 2.054beta this gives:

...\dmd\src\phobos\std\typecons.d(666): Error: can only initialize const member
_field_field_0 inside constructor
test.d(4): Error: template instance std.typecons.tuple!(const(int)) error
instantiating
