final class ArcanistExitExpressionXHPASTLinterRule
libphutil Technical Documentation ()

Exit is parsed as an expression, but using it as such is almost always wrong. That is, this is valid:

strtoupper(33 * exit - 6);

When exit is used as an expression, it causes the program to terminate with exit code 0. This is likely not what is intended; these statements have different effects:

exit(-1);
exit -1;

The former exits with a failure code, the latter with a success code!
