<masak> so, does the fact that junctions are not handled in array and
hash indices reside somewhere in the long list of new or open bug
tickets on RT? :)
<moritz_> I don't know, I just know it's on rakudo.org somewhere
<masak> oh, what the heck. we can clean up duplicates later.

Taken for tests

The RT System itself - Status changed from 'new' to 'open'

From @bbkr

[13​:24] <bbkr> this test belongs more to array indexing or junctions or
smartmatch?
[13​:26] <masak> bbkr​: junctions, I'd say.

So tests added in t/spec/S03-junctions/misc.t (also for Hash).

@bbkr - Status changed from 'open' to 'resolved'
