But why templates?!?!?
How is that different from ...
struct S3
{
const(int) member1;
const(float) member2;
const(bool) member3;
}
No template involved.
I'm reading Walter as saying that if any struct definition involves any of
its members being const/invariant, then one must define that struct in
terms of templates. Is this what Walter is really saying?
