Comment (by nomeata):

 Is anyone still pursuing this?

 I was just tossing the idea in my head of proposing multiple block
 arguments akin to
 {{{
 foo
   • one complex argument
   • second complex argument
     even on multiple lines
   • third complex argument
 }}}
 (with maybe not precisely this syntax), but if we had `ArgumentDo` I could
 smiply write, as was pointed out in
 [https://ghc.haskell.org/trac/ghc/wiki/ArgumentDo#Multipleblockarguments
 The wiki proposal],
 {{{
 foo
   do one complex argument
   do second complex argument
        even on multiple lines
   do third complex argument
 }}}
 and I would have no need for a separate proposal…
