valid through ALLOW_REGISTER flag and REGISTERS lexical state.

>    Affects Versions: 2.0
>            Reporter: Henri Biestro

>            Priority: Blocker
>             Fix For: 2.0.1

> When caching is enabled, a cached array expression using an integer literal will fail
at evaluation, the integer literal throwing an exception trying to coerce a ListGetExecutor
to Integer.
> Sole workaround is to disable cache entirely which is not always possible; critical!
