#3I’m not sure this page loaded properly for me, half of it is arbitrary punctuation characters assembled in bizarre nonsensical ways.

My brain immediately reached for the word 'horrifying', with phrases 'terrible consequences' and 'halting problem' soon after, but to each their own.

The detecting of increments has been in Perl6 for ages so that's not new. [edit Perl6 not Perl)
I guess (apart from the Whatever), the laziness is new since Perl6/Raku.

#6> (2, 30, 4, 50).map(* + *) returns (32, 45)
Should it be `returns (32, 54)` ? i.e. 4+50 for the 2nd term.
Maybe this is a consequence (head translation) of some countries saying e.g. vierenvijftig (four and fifty) instead of the English fifty-four.

#7It is absolutely mindbending to me that all of this language development has happened on top of Perl, of all things.

Why "of all things?" The Perl philosophy of TIMTOWTDI, and Wall's interest in human-language constructs and the ways that they could influence programming-language constructs, seem to make its successor an obvious home for experiments like this.

#9Wow. Sign me up for leaving the industry before I ever have to maintain a Raku codebase.

But this is detecting that the increment is multiplicative, rather than additive. It might seem like a natural next step, but, for example, I somewhat suspect (and definitely hope) that Raku wouldn't know that `(1, 1, 2...*)` is a (shifted) list of Fibonacci numbers.
