Hi Frank, On 1/10/11 6:45 PM, Frank Siebenlist wrote: distinguish an unassigned entry from a non-existing one. It would be great if that could be addressed. Don't you think that distinction does not belong into Lua? It's clear what it's good for but it is far from evident to anybody not programming for a living I think. So how do you spare everybody using Lua from having to understand that distinction then. Best, Henning |
