This is exactly what I meant by "extreme". I've never said that
semantics are irrelevant, yet you're taking something that you don't
like about my opinion and you're twisting it into something completely
different. You can do "not_null" in any of the following ways:

    $var !== null
    ! is_null($var)
    isset($var)
    ! empty($var)

I said, in the context of this thread, that semantics alone can't
justify the existance of yet another way to achieve the same goal.
Quite frankly, the idea that a programmer, regardless of knowledge or
experience, wouldn't be able to easily understand any of the above 4
expressions is absurd.

Cheers,
Andrey.
