The 1st/2nd Perl 6 solution is interesting because you read it from left to right treating map,grep and sort as object methods.

The Perl 5 version is read from right to left treating map,grep and sort as functions. I've attempted to do it the functional way in Perl 6 and got the following to work on Rakudo.

use v6;
say reverse .words for
     map {.[1]}
     ,sort( map { [.words[*-1],$_] }
            ,grep {/SRC1/}
            ,lines() );

The syntax for doing Perl 6 functionally seems to be more untidy than the Perl 5 version and make it a bit harder to read. The required comma, the required parenthesis around sort. Its not too bad though. Will get some getting use to.
