11925	using namely understandable placeholders	DarkTrick@…	Joel de Guzman	"'''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.
