//! Simple program for testing multi-statement glob matching and rewriting. Best used with
//! `test_replace_stmts`, which takes a pattern and replacement as string arguments. Examples:
//!
//! __m_stmts; -> __m_stmts;
//! __m_stmts; __s; -> __m_stmts;
//! __m_stmts; __s; -> __s; __m_stmts;
//! __s; __m_stmts; -> __m_stmts; __s;
//! __s1; __m_stmts; __s2; -> __s1; __m_stmts; __s2;
//! __m_stmts1; y = __e; __m_stmts2; -> __m_stmts1; __m_stmts2;
//! __m_stmts1; __s; __m_stmts2; -> __s
