Even though the replace function documentation already states that $$ should be used instead of $ in configuration files, the specific use case example does not emphasize this distinction. This can easily lead to misunderstandings, especially for newcomers. Since many people will use this in configuration files, I believe it is necessary to explicitly clarify the different usage in the specific use case example.
