Sorry slightly off topic, but I wonder if it's ok to be able to
redefine Regexp#=~ if YARV's optimization is disabled.
Is it intended?  Should the optimization flag be considered as
`Easter egg'?

$ ./ruby -e '
VM::InstructionSequence.compile_option = false
eval %q(
class Regexp
  def =~(x)
    p :called
  end
end
p /b/ =~ "abc"
)
'
:called
:called
