Invoking a regular expression engine is overkill for cases when the search pattern only involves static patterns.




NB: for stringr functions, that means wrapping the pattern in stringr::fixed().

NB: This linter is likely not able to distinguish every possible case when a fixed regular expression is preferable, rather it seeks to identify likely cases. It should never report false positives, however; please report false positives as an error.
