Are caguht exceptions global?

Hi

In rescue clause we can get to thrown object by variable $!
'$' prefix suggests me that this variable is global, but when I'm trying
to access it
beyond rescue block I got Nil class.
I think this is good behavior, but is this means that not all variables
that begins with $
are global?
Or maybe $! is global, but it's being NILed when exiting rescue block
(but why it's global then?)

begin
raise Exception.new("error message")
rescue Exception
puts "Something went wrong ("+$!.inspect+")"
end

puts "Something went wrong ("+$!.inspect+")" # <- NIL Class


Thanks for any answers
