I don't recall reading Keith saying any such thing.  He said he would
be willing to nit-pick a proposal for a new "for-loop" syntax - not
that he would welcome it.  Perhaps he just thinks he would enjoy
nit-picking such a paper.  As for using a feature if it were added to
C, I know I probably would do so in my own code - that does not imply
that I think such a feature is needed, or that I have any trouble
using C's current syntax for simple loops.  (I find C++'s alternative
for-loop syntax nicer for iterating over containers, but that is not
as easily translatable into C.)

Here's what I wrote:

"""
Again, I would not object to adding a new kind of for loop,
similar to what you would prefer, and visually distinct from the
existing for loop, in a new version of the C standard.  But that's
not likely to happen because there doesn't seem to be much demand
for it (for reasons that I know make you angry), and I don't care
enough to write a proposal.  If someone else does write a proposal,
I'll be glad to help out by nitpicking it.
"""

I'll accept that "cautiously accept" is close enough to "would not
object".

I guess I am the exception - I've never needed any of these.  But for
your information, C23 has a _Lengthof operator

C23 does not have _Lengthof.  It's proposed for C2y.
