Yes, and the people who are going to be using the LNUM patch and 
programming for the embedded systems for which it is most useful (for 
speed and storage reasons; 'efficiency') will probably be experienced 
enough to avoid possible errors arising from the conversions.

If you're developing using an LNUM-patched Lua, it'd be a good idea to 
always test your code under unmodified Lua as well as the LNUM-patched 
version to make sure there are no discrepancies in the results.  Test 
suites, although extensive, can only go so far, and there are bound to 
be specific cases (as Roberto showed) that can escape the otherwise 
passive change.  Testing your own code in both number systems is the 
most thorough way to identify any bugs that are caused by it.
