  • my @pascal := do [1], -> @p { [0, @p Z+ @p, 0] } ... *;

    (The extra do required because of a shortcoming in Rakudo.)

    FWIW, I think parentheses will work here also.

    my @pascal := ([1], -> @p { [0, @p Z+ @p, 0] } ... *);


    • Aye. I considered both forms, and went with the do form.

      When binding has list precedence, neither parentheses nor the do will be needed.
