I use 0.18.0, so the results may differ, of course. When running in the
browser, I get the same results as with version 0.18.0.
Maybe the compiler does some optimization but it cannot consider that _a_ and
_b_ are not used in another place: they are used by _echo_.
Assigning with **var** works, of course, so, it 's clearly an optimization when
assigning to a read-only object. I suppose, this has been done for performance
reason.
I have tried with version 0.17.2. Indeed, I get a strange result in the first
case, i.e.
@[0, 1, 2, 3]
@[54014246935360, 1]
So it seems that some bug has been fixed in version 0.18.0. For the other
tests, the results are indeed the same.
