"Nothing is gained" was Andreas's argument, not mine.

I don't want a function called from half a dozen places, which
generates a string from at least 3 different object types, to become a
cause for an assertion violation or worse.  It is a large and
not-so-simple function, where drawing such conclusions could yield
mistakes.

So let's please stop this particular bike-shedding and leave the code
alone.  There's nothing wrong with it.
