`say` concatenates the `.gist`s of each of its arguments.
I forgot to mention one other shortcut that is always available
if you do have to use `.new` (which is the case for most types).
You can write:
```
my $foo = 42;

The `42` on the RHS of the `=` is the shortest way to create
an integer value corresponding to `42`.
But you could also write:

That won't match just a slash (`/`). Maybe:

And it'll treat `/a/b` and `/a/b/` as distinct if the input string is `/a/b/`.

As others have noted, you need `%%`
TL;DR Raku does not treat a negative index as valid. To specify the index
of the last element, write `*-1`. What you're seeing is Raku trying to inform
you that you are using invalid indices.

You can put any Raku code that produces a string

So this displays `True`:

Btw, I had misunderstood ERN when, in 2018, I wrote the email
message I linked in the Note section of my previous email.
ERN is an intuitive sense that some movement you are initiating
is in some way a mistake. For example, quoting keys of a pair.
It's often unconscious, and, aiui, ignoring it

Thanks for that feedback, it's very helpful. I enjoy trying

I'm not yet convinced the issues you showed are classifiable as bugs.
Part of my reasoning for my conservatism is per the guidance Larry
provided in the design docs. In particular, per design doc S02:

My 2c is that I agree that that needs to be addressed.
I currently see that as something to first address via sprintf.

To quote Wikipedia, "A floating-point number is a rational number".
Rob wants to compare a float with its exact equivalent rational and
get True if they're exactly the same and False otherwise.

Except A) that's not what the doc says, and B) how does one

So it probably makes sense to ignore at least that part of my
previous email.

Aiui this is correct (and to me intuitive) behaviour described here:
https://docs.raku.org/language/numerics#Numeric_infectiousness
So if there's a `Num` (float) in a numeric operation (like `==`) then any
other number

I think the current flattening aspect is awkward in a couple ways:
* Having to specify ``. I half like Brad's suggestion.
* Having to write `.pairs` to extract

I can confirm your new test code also works fine in both program

Though obviously the case you mark as

Not the list, right? Just the rule. (There are dozens of kinds of
assertions. No one
is going to remember the list.) If you
And when I cut/paste from the doc, the number example works too,
in both script and repl.
