Daniel (>): > Related questions: What types of sequences can Perl 6 recognize?
As covered by Jonathan Lang earlier in this thread (though it was perhaps easy to miss), Perl 6 auto-detects arithmetic sequences (same additive difference each time) and geometric sequences (same multiplicative factor applied each time). Two terms are enough to seed the first kind; three terms are necessary for the second kind. If you supply three terms that follow neither an arithmetic or a geometric sequence (and doesn't contain a Callable as its last term), Perl 6 throws up its hands and doesn't try to guess. If you ask me, auto-detecting arithmetic and geometric sequences, but nothing else, is pretty much the sweet spot. We don't want to put more in CORE. The one that comes up most often as a suggested addition is the sequence of primes. Mostly just to mess with people who try it. :-) // Carl
