Hi David, The array element is not actually being accessed. The indexing is only used to compute an address. ANSI C allows references to the position "just after" the array's last element, so that th

First off, the "array part vs hash part" has nothing to do with this .. that is purely related to an internal optimization Lua uses in its implementation of tables. It?s a common mistake to suppose

(Sorry, this is going to be a bit long) Yes, this is true for a vector. Sorting is the action of shuffling the values inside the internal implementation so that whatever iterating algorithm we use p

Indeed... I have a friend that works on a commercial game engine that uses Lua. The "mismatch" between Lua array conventions and the convention used by the underlying C++ engine is one his number-one

I believe that one-based indexing was very intentional. Most people (who haven't had their minds warped into conflating ordinals with pointer offsets) expect the third item in a list to be #3. That'

Note, my use of "TLS" here is a bit abusive, because it is not strictly thread-local: objects referenced in closures or function environemnt is accessible in other threads by communicating them via y

For this reason, the generalization of the ":" pseudo-operator of Lua is not easy: it would create lot of overhead at compile-time and runtime to create many closure objects, that are compiled using

No, it returns what was in the variable x in the upvalue (i.e. the x part of the closure where it was compiled in scope), and not the x which may be defined anywhere else the function will be called,
