Disapointed because the author's link to the benchmark website lead me to the wrong impression that Lua would be almost 30 times slower than Java 7. Then I googled around and discovered the awesome LuaJit which seems to be able to compete even with C++ in performance.
What I really like is Lua's code density (see samples in the Shootout's benchmarks). Very impressive!

As an old LISPer and Schemer I would like to know if Lua Macros are really as expressive and powerful as Lisp macros. Some people claim this but I am not convinced (I would like to be convinced). The expressive power may be theoretically equivalent but this is also true for C and Assembler :-) The question is: Are Lua macros as easy to handle as Lisp and Scheme macros?
