Why do not call a 'record' a 'struct'?

Same with 'List' vs 'Vec'.

And why are List, String & co uppercase?

From what I gather these are built-in types the compiler knows?

'i32', not 'I32' but 'List' not 'list'? In Rust the case is clear cut: built-ins that the compiler 'knows' are lowercase, types expressed in Rust itself are PascalCase.

Roto seems to mix this?

Reads like Rust but then "differs subtley" where it (seemingly?) does not matter at all.

What is the rationale? I'm not complaining, Roto looks great. I'm considering swapping my Koto integration in my project out for this. :)

I'm just genuinely curious. From the outside the above smell like "just because" decisions.
