Rust

The general theme of your comment is good, but the example is...

The string “AAAAA” cannot be said to be greater or less than “AAAAB”

But in general the name “John” is not considered to be higher/lower than “Mark”

// rust
  eprintln!("{}", "AAAAB" > "AAAAA") // true
  eprintln!("{}", "Mark" > "John") // true

// C
  printf("%d\n", strcmp("AAAAB", "AAAAA")); // 1
  printf("%d\n", strcmp("Mark", "John")); // 1

strcmp() docs:

strcmp() returns an integer indicating the result of the comparison, as follows:

• 0, if the s1 and s2 are equal;

• a negative value if s1 is less than s2;

• a positive value if s1 is greater than s2.

So basically, if C had higher level constructs, it would be identical to Rust here.

So, even if it is cool to manipulate strings by using addition/subtraction, it is still bad language design and very unintuitive.

Rust has impl Add<&str> for String and impl AddAssign<&str> for String. Both append as expected.

But maybe you meant numeric addition specifically.

In that case, yes, Rust doesn't have that, although it's an impl<'a> Step for &'a str away from having something similar (it would be ("AAAAA"..).next()).

impl Step for char already exists of course, but shouldn't if we take your argument to its logical conclusion.

Oh, and C would most definitely have this feature if it could. Numerical manipulation of chars is commonplace there.

The string “AAAAA” cannot be said to be greater or less than “AAAAB”, besides the very special case when we order it.

I hate it to break it to you but it's the same with numbers.
