IMHO addition of %!+s and %!-s alone and removing %c's magic will 
only simplify formatting for the user. It was hard (for me) to 
understand current escaping rules because it's undocumented and 
looks dissonant (for me) because of the fact that escaping is a 
part of formatting but user is unable to control it unless 
magical %c is used.

I agree that !', !", and !?* of course aren't commonly used as I 
have already written. Personally I don't need them at all.

But this is a common pattern for me: `xformat("My pets: %(%!-s, 
%)", petsAsStrings)`. And "My pets: %(%(%c%), %)" is too 
complicated, dissonant and not general (will not work if I'll 
give it pets as int[] e.g.) that I never use it. I use 
`.joiner(", ")` instead and every time I do it I think that 
something is really wrong with array formatting in Phobos.
