I'd add :

- Change compiler design : build a new hookable AST-based compiler
that would allow modules (extensions) to hook into the AST for custom
compilation rules.

- Start a reflection about threaded VM : We could start designing a
threaded model and use it for I/Os at first. Our VM should be able to
do several things at the same time and we should prevent it from
waiting for operation results (I/Os).

- If we could redesign objects and arrays so that they could be
interchanged in many functions accepting arrays would be nice. Both
arrays and objects could share a common structure holding the data
that would be used when using such functions.

- Add new structures such as Generics, we need that

- Extend type hinting to scalars

- Improve PHP syntax so that compiler can make optimizations, such as
having allowing the declaration of read only variables : "public
static const $a".

More ideas to come...
