Re^3: [Perl 6] Returning Multiple Values

You're welcome!

I saw your corrections, but there is one point left I think.

In section Accepting values returned to you in the first invocation using ret-test'(5) the result of ($x gets 1 and $y gets 'Smith') is OK (according to the comment),

my (Str $y, Int $x) := ret-test'(5);  # y=>'Smith', x=>1, so OK
[download]

then in the third invocation the same result (as the comment suggests) is WRONG.

my (Str $y, Int $x) := ret-test(5);  # ($x,$y) gets (1,'Smith'), WRONG
[download]

So i assume it is WRONG but the comment has $x and $y (or the list values) swapped. And probably the same for the forth invocation.

The first calls ret-test-PRIME, which has the signature removed. But you are right, the comment is reversed. Worse than cut and paste: when trying to design the exact rules, it was different earlier. The use cases for pitfalls became the examples for why the Capture is reformed according to the Signature. I think I skimmed over the code block when proofing, too. I want to explain that better in prose. —John	[reply]
