OK: you changed the documentation to say "enclosing" rather than "current",
so it is now clear that the present behavior is the intended behavior. I
think it would be clearer still to say something explicit about needing a
`stop` in the code block for `loop` if you want loop to ever stop executing.
Here's why I find the intended behavior puzzling, and this bears on why I
was puzzled by the reference in the docs to the forever button. I expected
that there would be a command line equivalent to clicking a forever
button. The docs as they were written suggested that this was true: just
use loop. So I tried `loop [go]`, with a `go` protected in the usual way
by a stopping condition. Of course, this did not work as expected.
In sum I suggest the documentation I cited to be changed as follows:
Note: In most circumstances, you should use a forever button in order
to repeat something forever. In contrast to `loop`, a forever button will
stop looping if it calls a procedure that executes `stop`.
Or something like that. Finally, I wil note that the documentation of
forever button behavior is not explicit either.
http://ccl.northwestern.edu/netlogo/5.0/docs/programming.html#buttons
"Forever buttons keep running their code over and over again, until either
the code hits the stop
<http://ccl.northwestern.edu/netlogo/5.0/docs/dictionary.html#stop>
command, or you press the button again to stop it."
What it means for "the code" to "hit" the `stop` command is ambiguous.
