[Boost-users] [string_algo] split input parameter not const?

split() is declared as follows: template SequenceSequenceT & split(SequenceSequenceT & Result, RangeT & Input, PredicateT Pred, token_compress_mode_type eCompress = token_compress_off); Is there a reason why Input isn't const? It would be nice to be able to construct an iterator range in the call to split(), like this: typedef iterator_rangestring::const_iterator range; vector<range> inputs; split(inputs, range(Begin, End), is_any_of("\r\n"), token_compress_on); It's the same for find_all(), ifind_all(), and probably others, so there might be a good reason for it that I'm missing. -- Be seeing you.
