ups, should read mails more carefully! yes, that catches errors at run 
time only. It's not possible to do that at compile time without fully 
redesigning the language. However, that allows you to catch errors 
earlier, and provides a descriptive error message to let you know what's 
going on.

ie. If you use 'healht' instead of 'health' in your 'weapon_hit' 
function, at runtime you wouldn't know why can't you kill your target, 
but with the newindex metamethod those errors would show up as soon as 
the offending code is executed.

In my experience (that's not much :D), this kind of runtime checks and a 
proper test suite can be really helpful.
