Yeah, this should work, I think, though I would prefer the token last, latest, or recent. We would obviously have to be careful about exporting such a basic token. We would do something like
use PDL::Latest; $a->mv(0,-1)->rotate(3)->where(latest > 3); no PDL::Latest; The method would return the last piddle modified, which itself could be stored in the package global $PDL::last_modified_piddle. This gives function authors control over the "latest" behavior of their functions. It would also require that all current PDL functions would need to be retrofitted with this behavior. This short example seems like overkill, but in larger cases, or cases in which the user doesn't have conflicts, it would be nice.
