Come to think of it, I think that's good too - I can prevent people having
access to those nasty looking "raw" functions too. ;-)

Ok, it took me a few seconds to work out what that inject_math = inject
"math" stuff was doing but I've got it now, the stack gets inject, "math",
sandbox then the inject( "math" ) resolves to the function that takes
sandbox as its argument.

A Lua question, why isn't the syntax inject( "math" )( sandbox )... why is
it inject "math"( sandbox )?
