Consider the following two regexen and their matching output, or lack thereof: 11:39 < psch> m: say "abcd" ~~ /^(a | b | bc | cd)*?$/; my @a = < a b bc cd >; say "abcd" ~~ /^(@a)*?$/ 11:39 <+camelia> rakudo-moar : OUTPUT«「abcd」 0 => 「a」 0 => 「b」 0 => 「cd」Nil» S05 says: An interpolated array: / @cmds / is matched as if it were an alternation of its literal elements. Ordinarily it matches using junctive semantics: / [ $(@cmds[0]) | $(@cmds[1]) | $(@cmds[2]) | ... ] / Taking this literal still matches when written as the long form: 11:51 <psch> m: my @a = < a b bc cd >; say "abcd" ~~ /^( $(@a[0]) | $(@a[1]) | $(@a[2]) | $(@a[3]) )*?$/ 11:51 <camelia> rakudo-moar : OUTPUT«「abcd」 0 => 「a」 0 => 「b」 0 => 「cd」» With the S05 quote I'd expect the array to interpolate into any of the two other regexen and produce the same match.
