I think it sort of is.  My current preference would be that C-like languages
would simply absolutely eliminate optional-braces.  Then the whole category
of errors would partially-go-away.  You could still have code which didn't
do what you meant, but it would be reliably easy to see what it did, and
so on.  But it's interesting to note that there are many ways to address
this.

Most of the C I've done has been in circumstances where misindented code
was in fact a thing that would fail reviews.
