Channels and Class instance state: loop-earliest-more syntax results in shared state

[nxadm]

According to http://doc.perl6.org/language/concurrency#Channels, "[b]ecause looping over a channel in this manner [with $channel.poll and $channel.closed] is a common pattern there is a simpler functional syntax to do this", namely the "loop-earliest-more" syntax. The wording make it sound as both syntaxes should be equivalent.

However, the "loop-earliest-more" syntax results in an unwanted shared state between Class instances, while the classic syntax does not exhibit this problem.

See short runnable and commented code examples: https://gist.github.com/nxadm/6d867ad7410330d1bfac

This bug is reported here to know if this different behaviour should be documented (a feature ;) ) or just a bug.

Thank you,

It looks like there is a problem with closure on one of those blocks on the earliest, it looks like earliest is going to be removed at some point so I'll remove the earliest bit from the doc and do a better example using react

Doc seems to gave been updated.
