Right. So the instance data of the struct is more likely correct
when you call its methods.

That's a neat trick, although if preconditions were able to be
run at compile time when possible you wouldn't have to resort to
using enum to force CTFE (you've talked a bit about this before I
remember). Thinking about something like a good ranged number
implementation, we can now get almost

Thanks. - Well I'd like to see more of these tips. My current
code in D looks like C++ and of course I sure that I'm not
extracting the
void main() {
// Created at compile-time.
enum something = .Foo;
I don't think we should encourage UFCS with typenames or
uppercase names. If anything, it does not provide any benefit in
this case and Foo(.) is much more clearer without any
syntactical overhead.

In some D programs I'm using this coding pattern:
struct Foo {
// Instance fields here.
@disable this();
this(in string[] data) pure @safe
in {
// Many pre-conditions here.
} out(result) {
// Some post-conditions here.
} body {
// ...
}
