Hi all
To make myself clear, since I realise I used a confusing term in the subject of
my mail. What I'm proposing is runtime-erased generics, the way Matthew
describes them: PHP completely ignores them during runtime, and wouldn't do
anything with them during compile time. It's up to third par
I think the addition of runtime-erased generics would be a good thing for the
language.
I don’t think PHP should perform any sort of checking of generic parameters at
compile time. No other equivalent interpreter performs those compile-time
checks, and it’s also *very* complex — since adding su

No, the correct term is “type erasure”:

Its opposite is called reification:

Quick thing before I get into my own reaction:
Transpiling is normally thought of as the process of converting one
language into another. Tools like Babel transpile TypeScript to JavaScript.
What's being proposed here (AFAICT) is type erasure – the generic type
information would be erased during

Hello internals
Today I'd like to hear your thoughts on what might be a controversial topic,
though I think it's worth having this discussion. I want to make the case for
adding generic syntax, without actually enforing any additional type checks at
runtime. Please hear me out.
