Returns the size of a table, when seen as a list. If the table has an n field with a numeric value, this value is the size of the table. Otherwise, the size is the largest numerical index with a non-nil value in the table. This function could be defined in Lua: function getn (t) if type (t.n) 'number' then return t.n end local max = 0 for i.
The Lua core uses this option to set the size of the arg array, in functions with variable number of arguments; because the core cannot depend on a library, it cannot use setn. Another advantage of this option is that we can set the size of an array directly in its constructor, as we saw in the examples.
