If the objects are all unique, you can just use them as keys. No conversion necessary. I think the issue here is that he wants to create equivalence classes of objects. By the way, it would be a Really Bad Idea to use tostring(t) instead of just using t. tostring(t) is not going to keep t from being garbage collected, and if it were, some other object might end up with the same tostring() value. At any rate, it is completely unnecessary, since in Lua a key can be any Lua value aside from nil and NaN.On Tue, Jun 07, 2005 at 06:27:35PM -0400, Paul Chiusano wrote:In order for this to work, I need equal objects (according to __eq) to hash to the same location in the table.If these objects are strictly tables, tostring() might be sufficient for this already.
