[ruby-core:115994] [Ruby master Feature#16495] Inconsistent quotes in error messages

Issue #16495 has been updated by mdalessio (Mike Dalessio).


It may be interesting to note that the Prism parser has adopted a style guide for error messages, which avoids using the mixed quotes, and uses backticks around token literals to render well in markdown.

----------------------------------------
Feature #16495: Inconsistent quotes in error messages
https://bugs.ruby-lang.org/issues/16495#change-105959

* Author: Kolano (Kenneth Kolano)
* Status: Open
* Priority: Normal
* Assignee: matz (Yukihiro Matsumoto)
----------------------------------------
Error messages use inconsistent pairs of quotes, for instance:

```
-e:1:in `<main>': undefined local variable or method `foo' for main:Object (NameError)
```

where a back tick is used on the left-hand side, and a single quote is used on the right.

The same quotes should be used on either side of the elements being quoted.
