I assumed the .&foo form was just a nicer way of writing foo($_), however they 
differ in that
the thrown control exception doesn't go far enough in .&foo form and it doesn't 
actually
return from the routine with things like .&fail and .&return

    <Zoffix__> m: sub { 'foo'.&fail; 42 }().^name.say
    <camelia> rakudo-moar 64e898: OUTPUT: «foo␤  in sub  at <tmp> line 1␤  in 
block <unit> at <tmp> line 1␤␤Actually thrown at:␤  in sub  at <tmp> line 1␤  
in block <unit> at <tmp> line 1␤␤»
    <Zoffix__> m: sub { fail 'foo'; 42 }().^name.say
    <camelia> rakudo-moar 64e898: OUTPUT: «Failure␤»

    <Zoffix__> m: sub { return 'foo'; 42 }().^name.say
    <camelia> rakudo-moar 64e898: OUTPUT: «Str␤»
    <Zoffix__> m: sub { 'foo'.&return; 42 }().^name.say
    <camelia> rakudo-moar 64e898: OUTPUT: «Int␤»
