Hi together,

If a dev turns a file that he or she wrote into strict mode, then that

with ini settings. So don't shout out that nonsense FUD.
It's equivalent to an ini setting in that it changes the behavior of the
code based on something that is declared elsewhere. Obviously a declare
statement in the top of the file is a lot better than an ini setting,
but I think the principle is the same.
that is simply not true. The principle is not the same. The principle is
roughly the same as with namespaces. If you are unsure, got to the top
of the file, finished. Ini-Settings are runtime-dependent so there is no
way to find out what the ini-setting will be beforehand.
I don't think we disagree on this. I was only trying to say that both
ini settings and declare statements influence behavior of other code,
and that in both cases you have to put some effort into looking up the
current value, but that is where the comparison ends.
I think nobody will argue that namespaces are to complicated because you
can define the current namespace at the top of a file which than changes
the behavior of the file completely (which it does, somehow, by the way).
I'd never argue that namespaces are complicated, but they, like every
language feature, add a non zero complication to the language, whether
you would use them yourself or not.
Looking at the top of the file isn't a massive problem, but it is a
small one. If I didn't see the value in namespaces, I'd prefer not to
have them in the language at all (but I do, so I don't).
I'm arguing against statements like: "Well if you don't like strict
mode, don't use it.". It's not that simple. The fact that it exists adds
a cost.
