The greater prominence of Critiques in Calypso��
encourages me to try to clean them out.

I bumped into a false positive "Temporaries read before written."
that I've condensed to the following example.

�� test
�� |x|
�� [ x := nil ] whileNil: [ x ifNil: [ x := 1] ]

Now before I log an Issue, is it feasible to be able to recognise this?
Perhaps only for common looping idioms?

Anyway, the workaround is simple enough...

Hi Ben,

I do not have an answer regarding the variables written in the blocks, but for false positive you can also just exclude a rule for the scope of the method, class, package and image IIRC. There was a presentation at esug about it.��

I'm on phone and it's hard to search for the link currently.��

�� test
�� |x|
�� x := nil. "silence critiques"
�� [ x := nil ] whileNil: [ x ifNil: [ x := 1] ]
