doubt about sequence operator

[Luca Ferrari]

Hi all,
I'm misunderstanding the ... operator. The following works as expected:

    @seq = ( 1, 2, -> $a, $b { $a * 2 + $b % 2 } ... * )[^10];

while the following seems to loop infinitely:

    @seq = ( 1, 2, -> $a, $b { $a * 2 + $b % 2 } ... 10 );

Looking at <https://docs.perl6.org/language/operators#infix_...> I
cannot find an explaination of why the ending value of 10 is not
honored in the second case.

Thanks,
Luca
