in thread [Raku] Ranges in array slices

To make sure, we're on the same page, the sequence of even numbers can end:
> say 0, * + 2 ... $_ for 2, 10 (0 2) (0 2 4 6 8 10)
And if this was obvious, then - yes, that's the point. Sequences allow this kind of dissonances. No error is reported by the language. There's space for absurd. Or what should this be better called?

    I see no dissonance or absurdity here. The code creates two Sequences in a loop and they end because the end conditions (2 and 10) (the thing to the right of ....) get reached.
    If you create a sequence like 0, * + 2 ... 1 where the values go up and the end value is smaller than even the first calculated value, then that Seq. will can never end.
