throw(p1, p2 = v2)

Transfers control to the end of the active catch block waiting for tag. Raises UncaughtThrowError if there is no catch block for the tag. The optional second parameter supplies a return value for the catch block, which otherwise defaults to nil. For examples, see Kernel::catch.

{
    VALUE tag, value;

    rb_scan_args(argc, argv, "11", &tag, &value);

    UNREACHABLE;
}
