I need to separate templates:
```
foreach(member; __traits(allMembers, V))
{
static if (__traits(compiles, { auto _val = &__traits(getMember, value,
member); })
{
// a template needs to be instantiated to be addressable, so it works,
but I think it's dirty hack instead of dry and clean way...
}
}
```
May be phobos has such traits somewhere?
