I'm dreaming of a C with only pointers that has an optional VM (with and without GC) and namespaces, string and stream included.

You can cook your own (C++, WASM and Java), but if it was standardized and cross compatible.

Also curious why so many dislike streams?

Have a look at D.

I think I'm not going to like it because I want something that is foundational = works everywhere, is stable everywhere and has all features everywhere (f.ex linux 32-bit on ARM)

But I will give it a fair shoot.
