Re: When step is zero in numeric for statement

I can think of at least three reasons:

1) Loops are the most important things to optimize for performance. Any 
superfluous checks should be avoided.
2) "while true do end" does not throw an error.
3) "for i = 1, 1+e, e/2 do end" also does not throw an error. (Where e is 
the epsilon of lua_Number, ie the difference between 1 and the "next number" 
after it, for a given precision)
