/* The maximum number of levels of nested container which this implementation
* of #GVariant will handle.
*
* The limit must be at least 64 + 1, to allow D-Bus messages to be wrapped in
* a top-level #GVariant. This comes from the D-Bus specification (§(Valid
* Signatures)), but also seems generally reasonable. #GDBusMessage wraps its
* payload in a top-level tuple.
*
* The limit is actually set to be a lot greater than 64, to allow much greater
* nesting of values off D-Bus. It cannot be set over around 80000, or the risk
* of overflowing the stack when parsing type strings becomes too great.
*
* Aside from those constraints, the choice of this value is arbitrary. The
* only restrictions on it from the API are that it has to be greater than 64
* (due to D-Bus).
