I agree with this. If this were the only piece of C code that exists,
then of course its readability would behave as you say.

The other point is that readability depends on what the reader is used to,
or is familiar with.

      you what than way opposite the in written is that sentence a Reading
      its do cannot brain reader's the because Simply .hard is to used are
                                           .way usual the matching pattern

This is also the reason for the existence of the GNU coding style: code
is easier to read if it follows the usual visual and semantic patterns.
