Because they were implemented in Squeak, by saving, manipulating, and

No.. not without writing a Java interpreter that works differently than the
current VM. It's a mistake to assume Turing equivalence means all languages
have equal expressive power, they don't. I could mow my lawn with nail
clippers... But I'd rather use a riding lawnmower, but they're both
"capable" of doing the job; that's about all Turing equivalence really
