rev: 6c43f9

cmp works.
sort works.
coersion works.
wrong-dispatch works.
But, the last example makes (critical?) error.

<amoc> rakudo: my @list = 5,2,"9",True; say @list.sort: { $^a cmp $^b };
<p6eval> rakudo 6c43f9: OUTPUT«1259␤»

<amoc> rakudo: Code cmp 4;
<p6eval> rakudo 6c43f9: OUTPUT«Multiple Dispatch: No suitable candidate
found for 'cmp', with signature 'PP->I'␤in Main (/tmp/pXqBGHdfLN:2)␤»

<amoc> rakudo: my @list = 1,2,Code; say @list.sort: { $^a cmp $^b };
<p6eval> rakudo 6c43f9: OUTPUT«sh: ./perl6: No such file or directory␤»

I'm not sure it's rakudo bug. (it seems it's parrot bug)
But i report it here first anyway.

rakudo> my @list = 1,2,Code; say @list.sort: { $^a cmp $^b }
