Subject: Re: begining programmer questions

I'm a newbie to Ruby, but not to programming.

But the follow statement made by "Michael Gorsuch" is confusing.

"When you did 'info = gets.chomp', you wiped out your array and made it 
a
 simple String object."

I thought that Ruby was a strong typed language.
How can it change an Array to a String...I would have expected an error 
to be produced in this instance.

I would have hoped that once a type has been established for an object, 
the object would only adhere to the rules of that object...not change 
itself into a new object type.

I agree...this stuff can make you pull your hair out!!

Argh...
