This is Just Wrong, IMO. How confusing is it going to be to find that
calling is_prime($x) modifies the value of $x despite it being a very
simple test operation which appears to have no side effects?
As far as I can see it, in the example, it's perfectly logical for

The basic problem is that a junction does not work well with
boolean operations, because the answer is usually sometimes
yes and sometimes no and until you resolve which of those is
the one you want, you have to proceed with both conditions.
Well, just patch the boolean

This was nice feature at the time, but caused problems down the track

sure that is transitive in the first place... so that no matter what

What if junctions collapsed into junctions of the valid options under

Short answer: I don't think so.
Long answer: I tend to get very lost when dealing with junctions, so
I can be completely
Given that Perl 6 won't support an actual do-while loop a la C++ (and
yes, I know that Perl5 didn't either), how would you accomplish that?
That is, I'd like to have a loop that runs once, then checks its
condition to see if it should repeat and continues to repeat as long
as the condition is

Even if you fixed the =/and precedence with parens, to read
my $x = (any(2,3,4,5) and any(4,5,6,7));
then I think the result is still that $x contains any(4,5,6,7).
Funny. I thought $x would contain 'true' here, since Cand was a
boolean operator. But I could be very
