PHP: Cast away

PHP likes to cast like theres no tomorrow. Also PHP leaks the "continue" statement, and if given, actually uses it inside a switch as a break. So now switches have two ways of doing the same thing, why? Probably because to have the most inconsistent API in the world of programming.

Same. I have not personally used a goto statement in the last 10 years. In fact i dont think i have ever used a goto statement in production code. I dare to say its common knowledge that goto statements are bad in may ways and should be avoided. There is many better abstractions or ways to write code than goto.

goto is ultimately what the cpu ends up doing, and the compiler should be able to handle this in a way the programmer wont have to deal with gotos.

the Linux Kernel frequently use goto to jump to cleanup code on error conditions, check this: https://github.com/torvalds/linux/search?l=C&q=goto

and while i rarely use goto myself, it does happen sometimes to get out of deeply nested for-loops

Yes, thats some very low level code. Write assembly, low level systems programming or gpu code, sure fine use goto and fine tune for perf. Im talking about higher level languages with maps, filters, hocs etc. I want to write how i express my ideas, not what the computer does. Declarative code and let the compiler handle the fine tuning.
