Hi Gina, If it is mostly an implementation detail, this is probably ok. However, please make sure that `$foo = 'exit'; constant($foo);` (or any other future way to interpolate the constant) does not stop the program, but only fetch the value of a “real” constant. Alternatively, it is probably possible to keep the current parsing with T_EXIT, but to make it equivalent to invoke a “regular” function named `exit()` — somehow the same way that using the backtick operator is equivalent to calling `shell_exec()`, up to the point that disabling `shell_exec()` will also disable the the backtick operator? (BTW, it *is* currently possible to define and use a constant named “exit”: https://3v4l.org/aBq2R — of course, no need to keep such a “feature”.) —Claude
