It now works in Rakudo, as of 2012.03-5-g69920db:
> my @squares = 0, (-> *@a { @a.elems ** 2 }) ... *; say @squares[^11];
0 1 4 9 16 25 36 49 64 81 100
Also @_ now DTRT again:
> my @squares = { @_ ** 2 } ... *; say @squares[^11];
0 1 4 9 16 25 36 49 64 81 100
> my @triangle = 1, { @_[*-1] + @_ + 1 } ... *; say @triangle[^11]
1 3 6 10 15 21 28 36 45 55 66
Note that Rakudo also doesn't require a binding operation for the array...
assignment of detectably infinite lists (indicated here by the final
Whatever term) is supported.
