The assert macro is a more sophisticated version, which uses the built-in macros __FILE__ (which expands to the current source file as a quoted string) and __LINE__ (which expands to the current source line number, not quoted) to not only print out an offending expression, but also the location of it in the source. You might find g/**/g2. Using to_string() function.
