// ISO C++ 14882: 15 Exception handling
//

// This file declares functions whose only purpose is to throw an
// exception. They help break a circularity between <string> and
// <stdexcept>. See src/stdexcept.cc, where these functions are
// defined.

// XXX: These functions serve a similar purpose to those in
// stl/bits/stl_range_errors.h . Eventually the two approaches should
// be merged.
