* Include the source location in Closure names This change makes stack traces involving Closures, especially multiple different Closures, much more useful, because it's more easily visible *which* closure was called for a given stack frame. The implementation is similar to that of anonymous classes which already include the file name and line number within their generated classname. * Update scripts/dev/bless_tests.php for closure naming * Adjust existing tests for closure naming * Adjust tests for closure naming that were not caught locally * Drop the namespace from closure names This is redundant with the included filename. * Include filename and line number as separate keys in Closure debug info * Fix test * Fix test * Include the surrounding class and function name in closure names * Fix test * Relax test expecations * Fix tests after merge * NEWS / UPGRADING
