Now I understand better.
You'll need something more subtle. For example take `a = math.sin(b)`.
The expected result is obvious, but the approach you suggest would
stop parsing before the dot and assign the `math` table to `a`.
A possible solution would be to compile each statement as a chunk,
i.e. wait for a semi-column or the beginning of the next statement to
compile the last one.
It should be possible to patch the parser to that end, but I haven't
looked at it in a while so I can't guide you...
