map, grep and join are subs as well as methods. Perl6 is a multi-paradigm language and of course there's more than one way to do it - even when using the same operations. Instead of chaining methods, one could also use # p5 style join "\n", grep ?*, map *.description, @list; # dataflow style @list ==> map *.description ==> grep ?* ==> join "\n"; join "\n" <== grep ?* <== map *.description <== @list;
