I don't think it was quite as bad as that. If I
remember correctly, when you took a substring
you didn't get a view of a view, but another
view of the underlying layer holding the
characters. And there was some way of detecting
when parts of the underlying buffer were no
longer used and freeing them.

One strange thing Snobol did do was effectively
intern every string, though. And it had some
weird-assed name for them like "natural variable"
or some such...
