[boost] boost::algorithm::split design rational question

Hello,

When we look at the following declaration :

template<typename SequenceSequenceT, typename RangeT, typename PredicateT>
SequenceSequenceT& split(SequenceSequenceT & Result, RangeT & Input,
PredicateT Pred,  token_compress_mode_type eCompress = token_compress_off);

Anyone knows why split() takes the input type by reference and not by const
reference ?
The current design prevents, say, passing a temporary string to split which
is imho something not convenient.

I'd want to be able to do code like :

string input = "/foo/bar";
vector<string> tokens;
split(tokens,  input.substr(1), token_compress_off);

Thank you for your answers.
Philippe
