Bug #519 next() returning false on end of array

According to the documentation and according to my experiments, next() "returns the array element in the next place that's pointed by the internal array pointer, or false if there are no more elements".

Unfortunately, the array element returned by next() may be false or the empty string. It is undecideable, if this is an  array end or an array element, making next() somewhat useless.

Perhaps a real bottom symbol (like perl's "undef") would be appropriate.

If you want to traverse an array like this, use the each()
function.  There is an example in the FAQ.
