Indeed, but I don't really think the lack of 'very magic' is the
problem. :-)

I've never really found it very useful. It makes the simple cases a
little 'neater' but not really any easier to read.

\v$%(deferr|defout|stderr|stdin|stdout)>

$\%(deferr\|defout\|stderr\|stdin\|stdout\)\>


As for the more convoluted cases, is this:

\v\w@<!%(\?%(\\M-\\C-|\\C-\\M-|\\M-\\c|\\c\\M-|\\c|\\C-|\\M-)=%(\\\o{3}|\\x\x{2}|\\=\S))

really any easier to read than this:

\w\@<!\%(?\%(\\M-\\C-\|\\C-\\M-\|\\M-\\c\|\\c\\M-\|\\c\|\\C-\|\\M-\)\=\%(\\\o\{3}\|\\x\x\{2}\|\\\=\S\)\)
