This is something we've been backpedaling a bit indeed. 0.11 changed some things to look a lot more like Rust. The reason for this being different in the first place is that were not trying to make Rust-but-simpler necessarily. Or target audience with Rotonda is also not Rust programmers. So we've been exploring different syntax options.

Regarding the List type, as we optimize that, it will probably become a different data structure from a Vec. Also in the Roto-Rust boundary, you cannot pass in a normal Vec. So different names male sense there.

Regarding the case, small primitive types are lowercase. String and List are heap allocated and therefore somewhat different. I'm open to changing that but there is some logic to it.
