Any *competent* C programmer should know ??? Come on, have you *ever*
seen this weird construct used outside of the IOCCC ?
(Maybe this is a serious question... As for me, I don't remember having
ever seen it elsewhere).

What is its incidence on reality, as defined by programs written to accomplish
something and not to obfuscate ? Knowing the symetry of C arrays is fun,
but there are loads and loads of more useful things that a C programmer
should know first and foremost. Why not consider trigraph knowledge a must
as well ?
