Or rather, while I can manage to read an explanation of what one of these operators does and see how it applies to the variables in the examples next to it, I am struggling to retain a feeling of _why_ I would want to use any of these operators in real-life Perl 6 code. Please could the proponets of the various behaviours being discussed here share a few more concrete examples which start by explaning a scenario in which there is a desire to do something, preferably one that Perl 5 coders can identify with, and then show how one of these new operators would meet that desire (and that without that operator it would be hard or clumsy to achieve the same thing)? Already in Perl 5 having 2 different equality operators is something that learners often stumble over. If we're going to have 5 of the things in Perl 6 then there needs to be a very clear way of explaining how to determine which one to use (or at least an explanation that 3 of the operators are very esoteric and beginners don't need to worry about them).
