I want to preface again that I have only recently started giving the
language aspect of p6 serious focus. Without doing any digging into
junctions and pretty much just listening to the buzz, I not only think
of things like being able to verify that a userid isn't on a
blacklist, I also think of the ability to do things like:
1. Give me all the items in list A that match any of the items in list B
2. Give me all the items in list A that aren't in list B
3. well - you get the idea
I don't want to have to invent some special purpose infix operation to
do it nor should do I believe it should require much thinking. That
doesn't mean it needs to be in the core. If not in the core, I think
it should be generalized and included in one of the first available
modules. FAQs such as union, difference, intersection of lists are
FAQs for a reason.
Of course, it is real easy for me to say "it should 'just work'" from
where I am sitting - you all are the ones that have done the hard
work. Having answered the questions enough times in p5 circles
though, it would be nice to have a real simple easy answer for p6.
