The first use case that came to mind was JSON deserializers, where the
obvious mapping of null to nil causes problems with arrays.
But I think that's irritating mostly because superficially it _seems_ like
such a trivial (and trivially fixable) mismatch between Lua and JavaScript
type semantics, but as the thread has shown it's not trivial at all. I
wouldn't use this case to argue for change in Lua.
