Feature #4818: Add method marshalable?
http://redmine.ruby-lang.org/issues/4818

Some objects can not be marshaled. Maybe there should be a method to tell it.

hash = Hash.new {|h,k| k * 2}

this hash can't be marshaled because it has a default proc. If existing such method:

Marshal.marshalable?(hash) #=> method "Marshal.marshalable?"
hash.marshalable? #=> method "Kernel#marshalable?"

If you think the method name hard to spell, maybe get a synonym "dumpable?"
