Re: Advantages to passing a hash to a subroutine?

Not only can you pass them in any order with a hash, but you can omit any number of arguments without ugly commas and empty quotes (if you were trying to preserve position):

foo('','','',123); # array

Another advantage is that the arguments are self-documenting with a hash.

Also consider passing your hash by reference.

Thank you toolic Can you give an example on how the arguments are self-documenting as compared to not using a hash? Thank you!	[reply]

I think I see the example of the self-documenting hash from tobyinc. It makes it more clear. `perform_wedding( official => $smith, wife => $jones, husband => $brown, );` [download]	[reply] [d/l]
