Description

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!
