✔ Cleanup edge-case integer overflow/underflow
✔ Support for strings with length >= 2^31 bytes in 64 bit builds.
✔ Parse error on invalid numeric literals
✔ Uniform variable syntax
$belongs_to['column']
// vs.
$this->{$belongs_to['column']}

Foo::bar()()
$foo()()

(...)['foo']
(...)->foo
(...)->foo()
(...)::$foo
(...)::foo()
(...)()
// two more practical examples for the last point
