Sebb commented on JEXL-79:
--------------------------
Wow, that was quick!
Looks fine to me.
Needs some more tests:
- empty array
- adding items beyond the original list (including leaving a gap)
- referencing missing items
Just occurred to me - might be useful to be able to delete entries.
Perhaps setting an entry to null should delete it?
> Add support for growable arrays (ArrayLists)

> JEXL now has fixed arrays. Trying to access a non-existent entry generates an
> Exception.
> Might be useful to allow for the creation and manipulation of growable
> arrays, e.g. using ArrayList.
> Writing to a non-existent entry should just create the value; reading should
> return null and empty.
> This would need a new syntax.
> Perhaps:
> list=[1,2,3,...]
> and
> emptyList=[...]
> I did wonder about using (), but that would clash with method invocation.
> Other ideas welcome!
