Subject: Could not understand this: 3.class is Fixnum or Class

I stored the class of a variable in a variable and later checked in a
switch-case. Instead of going into the Fixnum case, it goes into ELSE.

c=23.class  # => Fixnum

c == Fixnum #  => true

case c; when Fixnum; puts "YES"; else; puts "NO"; end

# => prints NO

# after much head-scratching tried this:

case c; when Fixnum; puts "YES"; when Class; puts "CLASS"; else; puts
"NO"; end

# prints CLASS

---
As a result of this I had to store the class as a string (to_s), so the
case could work.
Could someone explain what I am missing here.
Thx.
