There are million-line Rust projects now. Rust is obviously workable for larger teams.

C uses every one of those symbols.

I think you're talking about @ and ~ boxes. As I recall, those were removed the same year the iPad and Instagram debuted.

Take criticism better.

A language choice on a project means the veterans are indefinitely charged with teaching it to newbies. For all Rust's perks, I judge that it would be a time suck for this reason.

Browsing some random rust game code: [https://github.com/bevyengine/bevy/blob/8c7f1b34d3fa52c007b2...] pub fn play<'p>( &mut self, player: &'p mut AnimationPlayer, new_animation: AnimationNodeIndex, transition_duration: Duration, ) -> &'p mut ActiveAnimation {

[https://github.com/bevyengine/bevy/blob/8c7f1b34d3fa52c007b2...] #[derive(Debug, Clone, Resource)] #[cfg_attr(feature = "bevy_reflect", derive(Reflect), reflect(Default, Resource))] pub struct ButtonInput<T: Copy + Eq + Hash + Send + Sync + 'static> { /// A collection of every button that is currently being pressed. pressed: HashSet<T>, ...

Cool. Too many symbols.

That first "random Rust game code" is in fact code I wrote :)

It's the same amount of punctuation as C++, or really any other language with C-like syntax.

I think this criticism is silly. Here's what your first example would look like in a language with keywords (where reasonable, perhaps like C#) instead:

  pub fn play<lifetime p>(in out self, player: mut ref AnimationPlayer lifetime p, new_animation: AnimationNodeIndex, transition_duration: Duration) -> mut ref AnimationPlayer lifetime p

But, this is still confusing! Let's remove even more symbols, and make the syntax more obvious by removing abbreviations:

  PUBLIC FUNCTION Play
  LIFETIMES
    P
  PARAMETERS
    IN OUT Self
  Player AS MUTABLE REFERENCE TO AnimationPlayer WITH LIFETIME P
  NewAnimation AS AnimationNodeIndex
  TransititionDuration AS Duration
  RETURNS MUTABLE REFERENCE TO ActiveAnimation
  BEGIN
  ...
  END

IMO, using keywords instead of symbols for references, lifetimes, etc, would just make Rust overly verbose, and there's a reason BCPL used braces instead of BEGIN/END :^)
