This morning I set out to convert four small programs and one mid-sized 
program to Lua 5.3

The small programs just worked (some of them had trigonometric 
functions, but they used math.floor() when the result had to be an integer.

The mid-sized program failed on a certain set of input data...
...but it turned out to be a mistake of mine three layers above: I 
forgot that a certain non-critical value was not guaranteed to be an 
integer and, as a consequence, a bitwise operation failed much later.
I could have 'fixed' it just before the bitwise operation to emulate Lua 
5.2 behaviour, but of course I looked for its root cause.

So, it looks like I worried without reason about possible fp/int 
problems, while in fact moving to Lua 5.3 has been painless for me.

Thanks for the excellent work on Lua... and for making me find an 
obscure bug ;-)
