Nathan Bubna commented on VELOCITY-533:
---------------------------------------

Ok, i've implemented support for size(), isEmpty(), get(int), and set(int,Object), as well as fairly thorough testing of the feature.  All tests pass.

Support for contains(Object), subList(int,int), and others may follow as i have time (anyone else is welcome to jump in here...).  I still haven't looked into support for auto-conversion between lists and arrays used as method parameters when the other is wanted.

> I'd like to see arrays treated like fixed-length List objects as much as possible.  This means auto-magically supporting size(), set(int,Object), get(int), and isEmpty() at a minimum.  Support for something like iterator() probably isn't necessary, since #foreach already handles arrays, but it might be good for completeness.  These should be possible via some Uberspect hackery.
> And since the goal is to free template authors from having to care about the differences between Lists and arrays, we might also consider supporting conversion between the two for method calls, so:
> $foo.wantsListHere($thisisAnArray)
> and
> $bar.wantsArrayHere($thisisAList)
> both work automatically.   I haven't yet looked into what it would take to do this.   If it is too hard or messy, i could be happy with just support for calling List methods on arrays.
