Lists inside a list conversion ([[]] to [][]int)

[hermanTenuki]

Python list [[1, 2, 3], [4, 5, 6]] to golang [][]int conversion causes all inner slices being full empty.

list1 = list_to_slice([intGo(i) for i in [1, 2, 3]])
list2 = list_to_slice([intGo(i) for i in [4, 5, 6]])
ls = list_to_slice([list1, list2])
ls_back = slice_to_list(ls)
list1_back = slice_to_list(ls_back[0])

Causes AttributeError: 'sliceGo' object has no attribute 'len'

With update #4, slices are hardcoded to work only with intGo, floatGo, stringGo, boolGo. Further rework is needed.
