Subject: Serialization ruby 1.8 vs ruby 1.9

Hi,

I am trying to marshal objects with ruby 1.8 and read them with 1.9 but
I get an error on date objects:
ruby 1.8:
f=File.new('/tmp/date', 'w+'); f.puts Marshal.dump(Date.today); f.close

ruby 1.9:
m=File.read('/tmp/date'); Marshal.load(m)

gives me:
class Date needs to have method `_load' (TypeError)

The versions of Marshal are identical, but in 1.8, Date has a _dump and
_load method, in 1.9 it does not.

Am I missing something or is this a bug?
Any hints are appreciated.

Thanks,
Florian
