There is a rather long discussion in incident
http://rt.perl.org/rt3/Ticket/Display.html?id=90886
about the switch feature (given...when and smartmatching)
It begins on 17 Mai 2011:

...and it stops (without a conclusion) on 30 Mai 2011

My question is quite simple: is there any progress made on this topic
since 30 may 2011 ?
