[q] is there a workaround to serialize a class instance

[vladp]

Created a simple class ( i ) exactly as described
http://lua-users.org/wiki/ObjectOrientationTutorial

then

local d=serpent.dump(i)
local fun, err=loadstring(d)
copy=fun()
print (copy:get_value()) -- attempt to call method 'get_value' ( a nil value)

The serialization does not know, I suspect, about the MyClass and its functions
is there a way to address it somehow?

thank you in advance
