Compiled code and input can get out of sync when quickly typing

[bjorn3]

For example if you enter

let a = 123459075670950985750895769789057u128;
let b = a+1;
println!("{b}");

and then place the cursor right between u and 128 and quickly press backspace and u, it will ignore the u and show.

error: literal out of range for `i32`
 --> main.rs:2:9

At the moment it's intentional.
This is caused by a check that ensures that executions can't be queued, to avoid big queues caused by quick typing.

I can increase the length of the queue, but then the experience for code that takes a long time will be weird (changes will not be reflected until much later).

Edit: I've just thought of a solution, to check if the input when the code was submitted is different than the current one, and run again if it's the case.
