Hah, a fun example of case sensitivity :-)

In your example you assign the class 'False' to the ok instance 
variable, not the instance 'false'. That is why I assume you get the 
behaviour you have, So the following should work as expected:

> ok _ false.
> [ok] whileFalse: [.... ok _ <condition>.]

The fun of having classes as first-class objects :-)
