Since whitespace in a charclass is not significant, then it should complain about an empty charclass, preferably with a hint about space. > <Zoffix> m: say " " ~~ m:s/<-[x ]>/ > <camelia> rakudo-moar 1aeea1: OUTPUT«｢ ｣» This matches because it's the same as m:s/<-[x]>/. You'd need to write <-[x\ ]> to make the space significant. > <Zoffix> m: say " " ~~ m:s/<-[ x]>/ > <camelia> rakudo-moar 1aeea1: OUTPUT«｢ ｣» Ditto. /jnthn
