Hi all,

I was wondering if there is a bug in BlockClosure>>isClean. As I understand it (see method comment below), the code below should evaluate to false as it closes over foo, but it does not.

Here is the comment for isClean: "Answer if the receiver does not close-over any variables other than globals, and does not ^-return (does not close over the home context). Clean blocks are amenable to being created at compile-time."

| foo| foo := Time now. [foo] isClean
