Now that we have `static foreach` I just realized we can

My recent definition now looks like
template allSameTypeIterative(V...)
// TODO restrict `V` to types only
{
static if (V.length <= 1)
{
enum allSameTypeIterative = true;
}
else
{
static foreach (Vi; V[1 .. $])
{
static if (!is(typeof(allSameTypeIterative) ==
bool) && // not yet defined
!is(V[0] == Vi)) // 10% faster than
`!isSame(V[0], Vi)`
{
enum allSameTypeIterative = false;
}
}
static if (!is(typeof(allSameTypeIterative) == bool))
// if not yet defined
{
enum allSameTypeIterative = true;
}
}
}
Is there a way to break the `static foreach` loop prematurely
as quickly as `allSameTypeIterative` becomes false?
Sure:
@property
bool allSameTypeIterative(V...)()
//if (allSatisfy!(isType, V))
{
foreach (Vi; V)
if (Vi != V[0]) return false;
return true;
}
No, it's not quite the same, but it's easier to read and gives
the same result.
