I prefer giving answers which I believe the asker will understand.

While there is something to be said for passing an anonymous hash if you have a lot of arguments, understanding that requires references, which someone who is still figuring out the calling semantics probably isn't ready to deal with. Also I hate leaving someone confused in a position where they feel, "I don't know why that didn't work, I don't know why this does, it is all magic to me." That leads to fear and cargo-cult programming.

However since you apparently do understand that answer, I'll give you another one. Read Pass by reference vs globals to see some of the issues that using references to hash arrays for lots of parameters can allow to grow...
