Hi Andrea,

I am probably going to ask a stupid question, but do we really need the 
=1 part in declare?

declare(strict_types=1) couldn't be declare(strict_types)?

Or does it mean that there would be cases when strict typing would be 
deactivated after being activated with declare(strict_types=0)?

To be honest, I don't like declare() because it looks like a function 
call, not a setting for the file like a namespace declaration would be. 
Also, in the case of declare(ticks=1), 1 is not a boolean but an 
interval so I find it a bit confusing that strict_types=1 would be a 
boolean in that case. Or maybe declare(strict_types=true) then?

Personnally I would prefer a syntax like:
declare strict;

which is just shorter and more readable in my opinion. I know it is 
mostly cosmetic but I don't really understand why declare uses 
parenthesis if it is a language construct and not a function (and yes, I 
think that declare(ticks=1) also looks silly ;) );

So basically instead of that at the top of my files:
<?php
namespace Foo;
use Bar;
declare(strict_types=1);

I would prefer having that:
<?php
namespace Foo;
use Bar;
declare strict;

It's probably a detail in the whole discussion, but for some weird 
psychological reason, it matters to me :),

Cheers,

Pascal
