I was using Net::Ping the other day and became irritated with the contructor. It would be fairly simple to just subclass it and add a own contructor but it got me thinking about how one would update the contructor and not break legacy code.
These are the first few lines of the constructor for Net::Ping. Not only would it be much "prettier" to use a hash in the contructor there are several settings with must be set via a method call. Of course I could just wait for perl6 then test 2nd param to see if it is a scalar or a slice but I'm assuming there must be some clever way of dealing with this now.
$proto, # Optional protocol to use for pinging
$timeout, # Optional timeout in seconds
$data_size, # Optional additional bytes of data
$device, # Optional device to use
) = @_;
