Code:
	def foo(bar, *baz, &block)
	  puts "trying to call foo #{@bar} (#{@bar.class.to_s.to_sym}) *baz = #{@baz} (#{@baz.class}) &block = #{@block} (#{@block.class})\n"
	  if (bar == nil) || (bar.class == NilClass) || [*bar].empty?
	  	puts "firing exception\n"
	    raise "There should be data here"
	  end
	end


program output:
	trying to call foo  (NilClass) *bar =  (NilClass) &block =  (NilClass)

question:
	How the function being called that the output is as shown without printing "firing exception"?
