//! Parse the root tokens in the rsx!{} macro
//! =========================================
//!
//! This parsing path emerges directly from the macro call, with `RsxRender` being the primary entrance into parsing.
//! This feature must support:
//! - [x] Optionally rendering if the `in XYZ` pattern is present
//! - [x] Fragments as top-level element (through ambiguous)
//! - [x] Components as top-level element (through ambiguous)
//! - [x] Tags as top-level elements (through ambiguous)
//! - [x] Good errors if parsing fails
//!
//! Any errors in using rsx! will likely occur when people start using it, so the first errors must be really helpful.
