Hi Fellows,

I've two questions to ask:

1) how do I compare an integer against let's say '\n' or ' ' 

   something like 

	if value == ' ' or value == '\t' or value == '\n' 

   I can do it for 'a' by saying ?a ... but how about special
   characters and whitespace ?

    
2) The function and subscription operators: how can I overload
   them. I'm using ruby 1.6.2. Am I out of date ?

Thanks in advance,

Frank.
