Subject: Re: Working with arrays

I'm not an expert and I can't tell you for sure what to do here, in my own 
bot I stored file contents in a variable name and then just rewrote the 
file, appending whatever I needed to the end of the variables contents and 
then writing the variable to the file. Anyways, back to my reason for 
responding, aren't globals slow in Ruby? a friend of mine from deviantART is 
always nagging about not using global variables... lol. Anyone feel like 
correcting him? And why are you passing in exceptions? :?
