Hi
The problem i see when using array() (or list()) is that it nearly looks
like it is a function, but it isn't. Using [] instead would clearly
mark this difference.
array() and list() are special language constructs, why shouldn't they look a bit
special?
This doesn't break backwards compatibility and it makes new code look
better and more readable.
