Because getn only works on tables used as arrays, not tables used as 
associative arrays, I'm afraid.

A table may contain some *numbered* items, and some *names* items. 
table.getn() (and the low-level luaL_getn()) both consider only the numbered 
items. In order to extract the names items you'll need to iterate through the 
table using lua_next().
