Well there's instance_variable_set, but this doesn't sound like a good  
idea. What if the work isn't a legal variable name (eg if it has a  
hyphen). What if the word is the same as some pre-existing instance  
variable ? This also makes it hard to iterate over all the instance  
variables set in this way. You'd be far better off bunging all that  
data in a hash
