You can omit spaces to make it look right to you.  I dislike
omitting spaces around operators.  So, without the internal
spaces, do you like any of them?

   if (any_of(...) <<some_predicate()>> 5)... // 1

   if (any_of(...) <some_predicate()> 5)... // 2

   if (any_of(...) ^some_predicate()^ 5)... // 3

   if (any_of(...) /some_predicate()/ 5)... // 4
