The problem with the exercise of translating a Perl 5 program to Perl 6 is that, unless you really know Perl 6 very well, you'll probably tend not to use all the power of Perl 6 (possibility of strong typing, function signatures, working given/when construct, pairs, junctions, enums, multi subroutines, construction of your own operators, grammars, etc.) and not to use really idiomatic Perl 6 code.

This is nonetheless quite useful to point out the differences between the two languages.
