Re: To Reference or not to reference

Chas,

You mention an issue that i've been pondering for a while. When and why should you
use an OO style instead of a hash? If your basic data structure (or several) is a hash,
what is to be gained by refactoring as OO? Isn't OO just a large amount of syntactic
sugar surrounding some simple data constructs?

I'm not being facetious or sarcastic. I characterize OO as "syntactic sugar" only as a
straw man to knock down. I really would like to know what people see as
the advantage to OO in this situation.

thanks,

better to pass the global hash by reference to each sub program to cut
down on possible typo errors or just leave it global and fix the problem
I have?

I can say with near 100% certainty that passing a ref is better than
using a global. Also, if you are finding your self writing code that
is focused around a hash that you are calling a number of functions on
then what you are really doing is writing OO code in a non-OO fashion.
Consider refactoring the code as object based instead of hash based.
