Consider the following two snippets:

21:03 <psch> m: .<A B C> >>=>> True given my %h; dd %h
21:03 <camelia> rakudo-moar 0b8e08: OUTPUT«===SORRY!=== Error while compiling
                /tmp/yQ1mgyWhDJ␤Missing << or >>␤at /tmp/yQ1mgyWhDJ:1␤------>
                .<A B C> >>=>⏏> True given my %h; dd %h␤    expecting any of:␤
                infix␤        infix stopper␤»

21:09 < psch> m: .<A B C> »=» True given my %h; dd %h # actually, never mind
21:09 <+camelia> rakudo-moar 0b8e08: OUTPUT«Hash %h = {:A, :B, :C}␤»

I would expect both to behave identically, considering the equivalence between 
>>=>> and »=».
