Putting $this-> and self:: is annoying , that didn't stop anybody from using
objects in PHP.

Maybe, but then I'll suggest that these aliases are accessed through
namespace:: or similar.

Please no. Just find the right one.

But you still know that $foo->bar is a member function call. That
information only makes code review and debugging a lot easier. The current
implementation of namespaces introduces a lot of uncertainty. I do not need
to tell you how hard and time consuming it is to debug or review C++ code. I
beg you, please do not make PHP a language that's as harder to debug or
review.
And even if you say "sometimes you need context", be prepared to be asked
"why now?".
Why context was not applied inside a class definition?
Why do I have to use $this-> or self::?
Why is there no with ($object) { ... } ?

So, every construct of a language works as a distinct unit?
There's no need to keep cohesiveness with how other constructs behave?
We'll have to accept that now there'll be statements that enforces a scope?
No problem then, I'll start training my brain to remember the namespaces and
imports of each file.
Maybe it makes sense in a language like Java that also enforces a directory
structure, but PHP?

Why would it lead to people routinely mixing different namespaces inside one
file?
Why is this bad in the first place?
Why is it the language the one to decide which is the better way to organize
code?
Also, that would not kill neither namespaced functions nor constants:
<?php
function namespaced::foo() {
...
}
const namespaced::CONST = "I'm namespaced!";
?>
