FUNCTIONS
cross
Usage:
cross(%args) -> [status, msg, payload, meta]Output the cross product of two or more sets.

Example #1:
cross( aoaos => ["1,2,3", "4,5"]); # -> [[1, 4], [1, 5], [2, 4], [2, 5], [3, 4], [3, 5]]
This is more or less the same as the cross CLI on CPAN (from Set::CrossProduct) except that this CLI is written using the Perinci::CmdLine framework. It returns table data which might be more easily consumed by other tools.
This function is not exported.
Arguments ('*' denotes required arguments):
aoaos* => array[array[str]]
Returns an enveloped result (an array).
First element (status) is an integer containing HTTP status code (200 means OK, 4xx caller error, 5xx function error). Second element (msg) is a string containing error message, or 'OK' if status is 200. Third element (payload) is optional, the actual result. Fourth element (meta) is called result metadata and is optional, a hash that contains extra information.
Return value: (any)
