With Rakudo commit bcc113cfb0 (Migrate combinations(n,k) logic to Iterator.Combinations) I get some aborted tests for combinations during spectest (running rakudo-j). I think it comes down to this failure: $ ./perl6-j -e '(2).combinations(0)' java.lang.RuntimeException: No such attribute '$!reified' for this object in method pull-one at gen/jvm/CORE.setting line 2931 in method sink-all at gen/jvm/CORE.setting line 2821 in method sink at gen/jvm/CORE.setting line 17172 in block <unit> at -e line 1 This works as expected, so the (0) case seems to be the culprint: $ ./perl6-j -e 'say (1, 2, 3).combinations(1..3).list.perl' ((1,), (2,), (3,), (1, 2), (1, 3), (2, 3), (1, 2, 3)) The full backtrace looks like this: $ ./perl6-j --ll-exception -e '(2).combinations' java.lang.RuntimeException: No such attribute '$!reified' for this object in pull-one (gen/jvm/CORE.setting:2931) in pull-one (gen/jvm/CORE.setting:2964) in sink-all (gen/jvm/CORE.setting:2821) in sink (gen/jvm/CORE.setting:17172) in <unit> (-e:1) in <unit-outer> (-e:1) in eval (gen/jvm/stage2/NQPHLL.nqp:1165) in (gen/jvm/stage2/NQPHLL.nqp:1255) in command_eval (gen/jvm/stage2/NQPHLL.nqp:1252) in command_eval (src/Perl6/Compiler.nqp:27) in command_line (gen/jvm/stage2/NQPHLL.nqp:1236) in MAIN (gen/jvm/main.nqp:47) in <mainline> (gen/jvm/main.nqp:38) in (gen/jvm/main.nqp)
