Currently, Mun only allows functions to be defined independent from a struct. We want to be able to associate functions with a struct type, as such:

pub struct Foo {
  x: f32,
  y: f32
}

impl Foo {
  pub fn new(x: f32, y: f32) -> Self {
    Self { x, y }
  }

  pub fn set_x(&mut self, x: f32) {
    self.x = x;
  }
}

The above syntax is hypothetical. An important question to consider is whether we need to have a special case for struct(gc) vs struct(value).

Similar to Rust, impl blocks for member functions can be spread across multiple source files.
