I believe an error would be possible, and I believe would be easier to debug 
then an occasional attempt to "x" on a nil value. Changing where the locals 
are effectively declared would result in loadnils (in the output code) where 
they really aren't necessary.

I believe Roberto/the authors worry that adding a continue now may well make 
future modifications to the language that much harder. Still, I'd go for 
one.

I don't know the compiler details. Would it be too difficult to consider 
local declarations after a conditional or unconditional 'continue' an error?

a block? For example, treat the given example code as if it was:
