Q::S is really a neat package, IMHO, but a bit of a mind-bender initially.
Obviously for their inventor too, since he apparently couldn't even get a simple example right in the docs! ;-)
I'm sure the module's new maintainer will update them accordingly for the next release.
Meanwile I do appreciate the bug report. One of the projects I'm currently working on is finalizing the semantics of Perl 6 junctions, which are an evolution of quantum superpositions. One of my goals is to simplify those semantics to make them a little more intuitive/predictable, and a lot less mind-bending.
Being able to watch your learning process in this thread has been of real value to me in doing that. Thank-you.
And thanks to tilly for the usual masterful explanations, for the bug report, and especially for drawing my (all too thinly spread) attention to this thread.
