For example Rust needs to be able to dynamically allocate memory for all of its syntax to be intact.

Hmm, you got an example of what you mean?

Rust can be used without allocations, as is for example commonly done with embedded.
That does mean, you can't use dynamically sized types, like String, Vec and PathBuf, but I wouldn't consider those part of the syntax, they're rather in the std lib...

So you're right that this is a bit arbitrary because the line between the standard lib and the language is blurry, but someone writing Rust is going to expect Vec to work, it doesn't even require an extra "use" to get it.

Perhaps a better core example would be operator overloading (or really any place using traits). When looking at "a + b" in Rust you have to be aware that, depending on the types involved, that could mean anything.

Anyway, I love Rust, it just doesn't have the 1:1 relationship with the assembly output that C basically still has.
