It is more to do with the goals of the Lua compiler. It is designed to
compile very fast and very efficiently in terms of memory usage. There
is no intermediate AST generation. As Roberto has explained in his
talks, Lua is a scripting language, and is designed to process large
data scripts fast - for example see the bug list maintained by Roberto
(https://github.com/lua/lua/blob/master/bugs).

There is an interesting project to perform bytecode optimizations
(https://github.com/Nymphium/opeth); something like could be used an
optional post compilation step (I would like to do this in Ravi).
