Using some existant C code could be more performant, of course. But this 
is about showing some »fine features«, not about showing the 
extensibility...

Currently, this could be an example showing sparse tables (?!), local 
functions, upvalues (closures) and some memoize technique.

Lua may be not the best utility for number theory, but this is just some 
kind of playground thing (like it would being asked on a PostScript 
list...).
