digitalmars.D.bugs - [Issue 23171] New: You can't use std.typecons.Typedef on __vector(*)


          Issue ID: 23171
           Summary: You can't use std.typecons.Typedef on __vector(*) type
           Product: D
           Version: D2
          Hardware: x86_64
                OS: All
            Status: NEW
          Severity: minor
          Priority: P1
         Component: phobos
          Assignee: nobody puremagic.com
          Reporter: leo.labruyere pm.me

import std.typecons : Typedef;
import core.simd : double2;

alias fooBar = Typedef!double2;

void main()
        fooBar foo;

The previous piece of code give the following error :
Error: expression `cast(__vector(double[2]))[nan, nan]` is not a valid template
value argument

Thus, it is not possible to create Typedef on vectorial type (or struct / class
with a vectorial type attribute)
