Unfortunately, it's impossible. We cannot allow iterating both mutable and
immutable objects by ModuleInfo.opApply, because it will cause type system 
violation. We should change the opApply signature all at once.

And compiler already place all ModuleInfo in read-only section. So modifying
ModuleInfo will cause segfault in some platforms. It's more worse.
