%params = %{ shift };

[download]
When I first read it, I thought it implied that shift in list context returns them all and empties the list; that is, gives the same value as %params= @_; but also empties out @_.

After reading Abagail's explaination, I see that he's passing a hashref as the first parameter, rather than passing names/values as individual parameters.
