Almost any formatting will do. At least I never care.

I assume those APIs would be used for very ad-hoc use (like the other APIs in Debug.Trace).

And debug codes put by such cases are deleted or disabled by NoTrace package in production.

I want handy default functions available without batteries.

Detailed formatting for debug messages should be configured by third-parties' logging libraries.

I am -1 on this. Such a function requires making a decision about formatting. What does a user expect from

> taggedTraceShowId "meganum" (42 :: Int)

Any of these are reasonable:

meganum: 42

meganum [42]

[meganum]: 42

In different applications I've worked on, I've wanted different flavors of something like this. Since there's no obvious choice, I don't think base is a good place for such a function.

Right, as I mentioned I'm not sure about the tagging idea. However, I
have found things of the form `(a -> String) -> a -> a` handy in the past.
Then again, it's pretty trivial to open-code this when needed.
