Coincidental correspondence between variable name and string literal is confusing #3803
Description
...if &"hello"[0] were valid code that returned the byte value, it would return 104, not h.
In chapter 8, section 8.2 shows an example of the indexing of a string as follows.
let hello = "Здравствуйте";
let answer = &hello[0];The original example has no double quotes. However, the double quotes appear in the text like what I copied. is that on purpose for any reason? Or, is that just a typo?

It may be misleading that the string within the sentence is ”hello”. I don’t think there’s any connection between this sentence and the code sample above. The point of the sentence is that indices on string slices are not allowed.
The string could be changed to: ”…if
&”abc”[0]were valid code […]”.[-]are double quotes added on purpose?[/-][+]Coincidental correspondence between variable name and string literal is confusing[/+]Fix confusion between variable `hello` and string `"hello"`

This was indeed confusing, so I changed the string example to be
&"hi"[0]instead of&"hello"[0], so it should no longer be an issue. Thanks!
