IMO, it is essential to offer DbC option without making the 'DbC-enabled'

I can understand motivation to write script runs in older release.
It's nice, I agree.

Personally, backward compatibility is not too important.
PHP5 is dead by PHP 7.2 release... This is the reason why.
It's only 3 years later, only 2 years later after PHP 7.0 release.
Therefore, I prefer PHP syntax based one. If it could be written as
normal PHP code, it would be great.

I prefer my proposal of course. However, I don't care much about
where it should be written. I only care we have clean/fast/native/easy
DbC support in PHP 7.

I thought you are going to write PHP syntax borrowed one.
For most users, PHP syntax is better. IMHO.
Since Dmitry offered something based on annotation, could
you work based on PHP syntax? and show us your concept on
this thread?

Regards,
