They're there for a very practical, rather than a very beautiful, reason. :-)
They are there to make:
say 'abc' ~~ m:g/\d/
And:
say 'abc' ~~ m:g/\w/
Do the right thing, and produce a List of Match results (which may be empty).
Even before this, it was decided that `4 ~~ (4,5,6,7)` should not magically
mean testing for inclusion in the list (I forget the exact reasoning, but
confusion when considering lists of lists would be one good one). There are
plenty of other ways to do that, such as:
say 4 (elem) (4,5,6,7)
So, ticket rejected since the current behavior is both serving an important
purpose and the proposed DWIMmery has, best I can recall, been tried and
rejected in the past.
Thanks,
