Add support for pickling object

[badochov]

Currently pickling go objects is not possible. I know that solving general case may be very hard but probably only supporting map, slice, string, int is good enough for most of the cases and possibly not that hard.

@sbinet would you be interested to help on this?

[sbinet]

you mean, being able to marshal simple Go values into a python pickle ? (that is, the reverse of what gopickle can do right now: python->Go).

sounds interesting (we kind of already do parts of that in go-python/gpython) but the whole marshaling infrastructure has to be put in place.

I personally don't have a use case (at least, not right now), so the incentive (and maintenance burden thereafter) doesn't sound too good :}
sorry.
