Subject: Question about callcc

Hi,

I'm trying to understand continuation.
There's some confusion in the following:

In top-level,

[1]
callcc { |c| $label = c }
#...some other code here
$label.call

[2]
$label = callcc { |c| c }
#...some other code here
$label.call


Are they same or different?
As I understand it, callcc returns the last expression or return value
of c.call.
Thus, basically [1] and [2] should be same, right?
But I'm not sure.
Can anyone explain it, please?

Thanks.

Sam
