[perl #77670] [BUG] .>>. no longer recognized as meaning the same as >>. in Rakudo

[Christian Bartolomaeus via RT]

As Matthew mentioned this works now. .>>. and >>. behave the same again:

$ perl6-m -e 'say ( { 1 + 1 }, { 2 + 2 } ).>>.().perl'
(2, 4)

$ perl6-m -e 'say ( { 1 + 1 }, { 2 + 2 } )>>.().perl'
(2, 4)

I added a test to S03-metaops/hyper.t with the following commit:
