#11925: using namely understandable placeholders
------------------------------+----------------------
 Reporter:  DarkTrick@…       |      Owner:  djowel
     Type:  Feature Requests  |     Status:  new
Milestone:  To Be Determined  |  Component:  spirit
  Version:  Boost 1.60.0      |   Severity:  Cosmetic
 Keywords:                    |
------------------------------+----------------------
 '''Current situation:'''
 At the time, placeholders have rather generic names (_a,_1,_r1,...). That
 leads to code like this (from the error handling tutorial):

 << _4                               // what failed?
 << construct<std::string>(_3, _2)   // iterators to error-pos, end

 This is hardly self-explanatory code.

 '''Suggestion:'''
 change placeholder names to humanly understandable phrases, where
 possible.
