 1. Doesn't error out on usage on invalid and non-existent variables, returns legitimate value for such.
-1. Numeric type is single, forced float. Inefficient w/o floating-point hardware (eLua works around by offering integer-only version, which then cannot support float). Problem with bitwise logical operations. Etc, etc.
-1. Container type is single, associative array (called "table"). (Latest version of Lua work that around by providing dynamic array-vs-map switching underneath.) Multiple issues due to this, like array indexing starting from arbitrary number rather than zero, "length" of table not always corresponding to number of elements in it, etc.

 1. http://www.tecgraf.puc-rio.br/~lhf/ftp/doc/hopl.pdf p.23 "We have resisted user pressure to include other data structures, mainly “real” arrays and tuples, first by being stubborn, but also by providing tables with an efficient implementation and a flexible design." Of course, what Lua developers call efficient implementation is actually *inefficient* implementation: "In Lua 5.0 we introduced a hybrid representation for tables: every table contains a hash part and an array part, and both parts can be empty. Lua detects whether a table is being used as an array and automatically stores the values associated to integer indices in the array part, instead of adding them to the hash part" (p.12). So, Lua wastes memory to store "two parts", then wastes runtime cycles to "detect" which one to use.
