After seeing this a couple years ago I started to be more responsible for my PHP code, writing it even with the slightest micro-optimizations possible, since more times people use my code (especially due to nature of PHP being executed in every http request), more energicity they waste because of my lazyness and more they pollute the planet. JIT was NOT included in this experiment, so the number can be much more lower.
I hope you will be responsible for your code so on too (generally I mean people using interpreted languages).
Measure the segfaults per line and the resulting effort to resolve please.
Rust was designed not to allow issues like that...
C/C++ on the other hand...
Was designed to promote issues like that (happy debugger noises)
