[sv-ec] 5.7 example question

Hi,

What do you say about the last example in 5.7 ?

QUOTE:
Similarly, the source of an assignment can be a complex expression
involving array slices or concatenations. For
example:

string d[1:5] = '{ "a", "b", "c", "d", "e" }; 
string p[]; 
p = { d[1:3], "hello", d[4:5] };

The preceding example creates the dynamic array p with contents: "a",
"b", "c", "hello", "d", "e".
:ENDQUOTE

Is the assignment to p in a legal form?

If so, why?
If not, how should it be done?

I got the following response from Brad Pierce:

"I think the committees agreed to "punt" on this issue, because no one
provided a detailed semantics for how it was supposed to work, and no
entity considered the issue important enough to vote 'no' over it.

As far as I know, there is no other way to get the splicing behavior of
that example.  Without it, you would need to write

      p = '{ d[1], d[2], d[3], "hello", d[4], d[5] };

But that methodology breaks down if the indices are parameterized
instead of simple literals.  In that case, the only alternative is to
use two for loops."

Thanks,
Shalom
