Reads a child item out of a container #GVariant instance. This
includes variants, maybes, arrays, tuples and dictionary
entries. It is an error to call this function on any other type of
#GVariant.
The returned value is never floating. You should free it with
glib.variant.VariantG.unref when you're done with it.
Note that values borrowed from the returned child are not guaranteed to
still be valid after the child is freed even if you still hold a reference
to value, if value has not been serialized at the time this function is
called. To avoid this, you can serialize value by calling
glib.variant.VariantG.getData and optionally ignoring the return value.
There may be implementation specific restrictions on deeply nested values,
which would result in the unit tuple being returned as the child value,
instead of further nested children. #GVariant is guaranteed to handle
nesting up to at least 64 levels.

It is an error if index_ is greater than the number of child items in the container. See glib.variant.VariantG.nChildren.
