Subject: Re: conversion issues

how about this cin>> = num, lol i dont know ruby seems like a trade off 
to me so far. i am just trying to understand all this hype about it. I 
mean every book i am reading says its the best most awesome easiest to 
use, just like using natural language, its elegant and beautiful and it 
will make you cry because its so easy to use, etc etc. I am having a 
hard time understanding that. If its true i would like to see it at some 
point.
