Code review comment for lp://qastaging/~james-w/launchpad/more-matchers

PublishedStateIsNot is a little weird to export, being a mismatch - might want to think about the clarity for users there.

PublishedStateIs would add more debug value if it included all the failing elements, not just the first.

Typo 'supecseded'

This could be a regular method, not inline.
+ def spr_title(spr):

DateIsInPast would be good to do upstream - its not launchpad domain specific at all.

Please consider these tweaks and recommendations.
