| 79 | Footnotes: the choice of <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">runtime_error</span></code> | |
| 80 | as the base class for <code class="computeroutput"><span class="identifier">regex_error</span></code> | |
| 81 | is moot; depending upon how the library is used exceptions may be either | |
| 82 | logic errors (programmer supplied expressions) or run time errors (user supplied | |
| 83 | expressions). The library previously used <code class="computeroutput"><span class="identifier">bad_pattern</span></code> | |
| 84 | and <code class="computeroutput"><span class="identifier">bad_expression</span></code> for errors, | |
| 85 | these have been replaced by the single class <code class="computeroutput"><span class="identifier">regex_error</span></code> | |
| 86 | to keep the library in synchronization with the <a href="http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2005/n1836.pdf" target="_top">Technical | |
