Compiling programs of a dynamic language like Lua was seen as hopelessly inefficient. But today programs running on the the Lua JIT are often faster than equivalent FP-heavy D programs compiled with DMD. 
So it's all in having a positive attitude toward technological problems: if the need to do something grows strong enough, people usually find a way to do it :-)
