Here's where I got a shock. I wanted to test the speed so I upped the

!!! WHAT!? how many? how the... That can't... DAMN! wow.
Why this is possible I can't say. I'm hoping Nigel or Chris will
comment on the underlying reason.
Here's a hint:
set s to do shell script ("echo '" & l as text) & "' | tr '" & delim &
"' '\n' | sort -f")
text items of s --> (an 8192 item list)
class of s --> Unicode text
Here's another hint:
text items of (s as string) --> Error: Stack overflow.
"Unicode text" doesn't suffer from the stack-imposed limit that
"string" does. In another release, neither will "string".
