Right, for this enhancement request the indentation is irrelevant.

See bug 4924 for something about indentation.

It is meant first of all as an error.

That's true if you are talking about a warning. But Walter doesn't like
warnings, and I think in this case a true error is acceptable. And if it's an
error, then it's part of the language, so you can't perform this change too
much late. In Bugzilla I have some other very small changes like this one that
are hard to do later.
