The idea is to provide single for loop structure for each of
the variables(in this case s and this).
You can do this with `std.meta.AliasSeq`:
string[] a = ["lions", "tigers", "bears"];
int[] b = [123, 456, 789];
static foreach(array; AliasSeq!(a, b)) {
foreach (item; array) {
writeln(item);

}
I tried that but it didn't work... I will try again.

In D, structs don't participate in inheritance. Classes do, but invariants
aren't inherited; they're specific to the class in which the function is
defined. (Which is probably a bug and I filed https://issues.dlang.org/
show_bug.cgi?id=19537.)
I see three ways to make this work today:
1. Use alias this to wrap the struct. Add invariants that deal with the
wrapped struct's fields.
2. Use compile-time reflection to copy the fields over, then manually copy
the invariants over and add more.
3. Use a class. Define a virtual function like 'doInvariant()`. Call it
from the base class's invariant{} block.

With classes, a derived class instance can be used anywhere you expect a
base class instance. The reverse is not true.

(which btw i also happen to use for my new blog http://dpldocs.info/this-week-in-d/Blog.Posted_2018_12_31.html ) I'll have to check that out. I wrote like 30 lines of code and very simple definitions to support all the languages in that test. And it is plenty good enough. Cool. And I can download this? I don't know if I'm being dim, but I really don't see how to. Of course, it DOES support D, extremely fully - it has a full-blown D lexer in there. But tbh if I use the C family highlighter for D you usually can't tell the difference. No doubt! :)

The is to avoid string mixins which are pathetic for this kind of
work.
The point is that instead of having to do
for(int i = 0; i < s.length; i++)
...
for(int i = 0; i < this.length; i++)
...
in which case ... might be very long.
Sure one can create a function and all that mess but the compiler
should be able to do symbol replacement very naturally and easily.

Low order hashes
I need to hash a few strings to a byte, short, or int. hashOf works for int only on x86. What would be a nice way to accomplish this? Collisions are not good but not catastrophic. Mainly I need a unique ID to emulate enums. I might just chop off the extra bits or mash them up somehow and it will probably work but hoping for something more solid.

I have a struct X in D. Is it possible to define a type
equivalent to X except that having tighter invariants?
As I understand if I derive Y from X, then it is no more X;
1. As Ada is strongly typed, this is the same there, no?
2. You cannot derive structs in D. Therefore, I assume, that you
meant that X and Y are classes.
that is I cannot use X (even provided it matches Y invariants)
where I need Y. So in D it is impossible, right?
It is possible, as invariants are inherited implicitly, see
https://dlang.org/spec/contracts.html#Invariants
paragraph 9.

import std.experimental.all;
void main()

auto x = new X();

Subtypes with tighter constraints
In Ada2012 there are "subtypes". Subtypes can have tighter constraints (such as type invariants) than their base types. I have a struct X in D. Is it possible to define a type equivalent to X except that having tighter invariants? As I understand if I derive Y from X, then it is no more X; that is I cannot use X (even provided it matches Y invariants) where I need Y. So in D it is impossible, right? I think in D it's impossible, but want to be sure and so ask.
