The short answer is no, not for any recent version of D.
The long answer is it's kind of

Class destructor also automatically calls destructors of struct

A template parameter is usually needed when it affects the output
data, but in case of regex it won't do much, because the output
data are slices of the input string, so decoding doesn't affect
them, only exceptions.

I see. I'll try to rephrase my question to be clear. We have:
```
struct Foo
{
int i;
float f;
}
int main()
{
const(Foo)[] cfoo = [Foo(1, 0.5), Foo(2, 0.75)];
Foo[] foo;
cfoo.copy(foo); // it works, constness no matter here because Foo is
value type
}
```
but
