I would have written it sub prefix:<∑> { [+] @_ } would you have liked it more? (I personally find it more "perlish")

  I've never written any Perl 6, so this comment could be badly foolish. As you point out, the suggested `∑` is just sugar (for some value of 'sugar') for `[+]`. In Perl 5, one could easily alias subroutines using, for example, `* a = \&b` (space inserted to fool Markdown). Is there any analogue in Perl 6, so that, say, `* ∑ = \&[+]` or its modern variant would automatically inherit the parsing semantics without having to go through the cumbersome process of declaring a new sub just to pass its arguments unchanged to an old one?

    [+] is not a function with a name, as it is the result of the metaoperator [] to the function &infix:[+]. Thus you really need a closure.
