I feel like there's a parallel with SQL where you want to discourage manual interpolation. Taking inspiration from it may help: you may not fully solve it but there are some API ideas and patterns.

A logging framework may have the equivalent of prepared statements. You may also nudge usage where the raw string API is `log.traceRaw(String rawMessage)` while the parametrized one has the nicer naming `log.trace(Template t, param1, param2)`.

You can have 0 parameters and the template is a string...

The point of my message is that you should avoid the `log(string)` signature. Even if it's appealing, it's an easy perf trap.

There are many ideas if you look at SQL libs. In my example I used a different type but there other solutions. Be creative.

    logger.log(new Template("foo"))`
    logger.log("foo", [])
    logger.prepare("foo").log()
