It is the point. Should we support a feature that will not help those
who are follow

Personally, I don't care for the concept of a block scope. I do
understand that it can have benefits and make certain tasks easier.
But it can also lead to weird bugs and inconsistencies. For example,
take the following code:
$good = false;
foreach ($array1 as $value) {
$good = $good & $val

Hi,
I've lately discussed with a colleague which scopes of variables exist
for PHP or would probably make sense. In general I think the general
idea of having variables available all throughout a function is okay as
this allows things like
foreach($vals as $v) {
// ...
$found = true;
}
if($fo
