When I input the following lines in irb, the irb terminates.

$ irb
irb(main):001:0> def !; end
=> :!
irb(main):002:0> !
/usr/local/lib/ruby/2.1.0/irb/input-method.rb:153:in `gets': private method `!' called for false:FalseClass (NoMethodError)
...
$

Indeed. I have a similar error but different:

def !; end  # => :!

/usr/lib/ruby/2.1.0/irb/init.rb:250:in rc_file': private method!' called for #Proc:0x00000001a19338@/usr/lib/ruby/2.1.0/irb/init.rb:273 (NoMethodError)

Somehow a Proc is called in my case. This happens when I type an empty newline after inputting the above code.
