Hi,

I'm trying to use Variant in a struct and want a default init value like so:

---
struct S {
  Variant v = Variant(10);
}
void main() {auto s = S();}

but when I try to build this I get the following error:

dmd2/linux/bin64/../../src/phobos/std/variant.d(661): Error: memcpy cannot be interpreted at compile time, because it has no available source code

Error: cannot interpret <error> at compile time

I don't particularly need or want this to be available at compile time, I really only want the struct to have a default value when instantiated at runtime.

Is there a way to do this with a Variant member?

Thanks,
Norm

Hmm... found something similar from 2014...
