Not as I understand it. x would be reachable by a Smalltalk garbage
collector, but not truly reachable by the program itself.
He could have just as well have written:
| x |
x := Something new.
true whileTrue: [ ..blah.. ].
x is unreachable by the definition given. It doesn't matter that a
tracing gc would know where it is in an activation frame, the program
will never access it.
