This is in no way D specific but say you have two constant

You could lay out the memory inside of one another. IE: if
a.ptr = 1 then b.ptr = 6. I'm not sure if this has been done
and I don't think it would apply very often but it would be
kinda cool.
I thought of this because I wanted to pre-generate
hex-representations of some numbers I realized I could use
half the memory if I nested them. (At least I think it would
be half).

I'm pretty sure this is called string pooling.
My understanding is that string pooling just shares whole strings
rather than combining suffixes.
e.g.
const char[] a = "fubar";
const char[] b = "fubar"; // shared
const char[] c = "bar"; // not shared at all
Combining suffixes is obviously possible, but I'm not sure that
string pooling implies suffix pooling.
