Subject: Re: Array#collect in a method call, not working for me

OK, I *thought* that part was working, but now I see that it wasn't 
really. So to help me understand I wrote the following, to see what it 
does and I see that adding the #inspect will give me the string to 
compare against.

But does that mean that (a = [1, 2].class) is setting a to be an Array?
Oh, and thank you!

Here is my test...

irb(main):034:0* def proovy( n )
irb(main):035:1>   a = n.class.inspect
irb(main):036:1>   b = n.class
irb(main):037:1>   puts "a: #{a}"
irb(main):038:1>   puts "b: #{b}"
irb(main):039:1>   case a
irb(main):040:2>     when "Array"  : puts "a matched Array in case"
irb(main):041:2>     when "Fixnum" : puts "a matched Fixnum in case"
irb(main):042:2>   end
irb(main):043:1>   case b
irb(main):044:2>     when "Array"  : puts "b matched Array in case"
irb(main):045:2>     when "Fixnum" : puts "b matched Fixnum in case"
irb(main):046:2>   end
irb(main):047:1> end
=> nil
irb(main):048:0> proovy(1)
a: Fixnum
b: Fixnum
a matched Fixnum in case
=> nil
irb(main):049:0> proovy([1, 2, 3])
a: Array
b: Array
a matched Array in case
=> nil
