Feature #16240: Are all objects and methods marshalable

As I work with objects, some of them are not marshaled. Maybe there should be a method to tell whether an object is marshalable or not.

See below example:

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?"

Thanks,

Matt
