hi, i've implemented an extended form of 'fill' algorithm that can handle multi-dimensional containers and would appreciate comments on whether: a) i've reinvented the wheel and such code is already available in boost, b) i've made some obvious mistake that my (admittedly minimal) testing hasn't found yet, c) it would be useful to anybody :) the code is given below (namespace declarations removed): template typename enable_if_c::value>::type fill(Range& range, Value const& value) { range = value; } template typename disable_if_c::value>::type fill(Range& range, Value const& value) { for(range_iterator<Range>::type i = boost::begin(range); i != boost::end(range); ++i) fill(*i, value); } comments appreciated, thanks, ian whittley
