For C in particular we have a "half-way between" mode where we allowed some
keywords (like `class`) even though we still used C++ reference semantics. So
for instance:
```
(lldb) run
Process 79429 launched: '/tmp/foo' (arm64)
Process 79429 stopped
* thread #1, queue = 'com.apple.main-thread', stop reason = breakpoint 1.1
frame #0: 0x0000000100000480 foo`main at foo.c:7
4 main()
5 {
6 int class = 100;
-> 7 printf("class is: %d.\n", class);
^
8 return 0;
9 }
Target 0: (foo) stopped.
(lldb) expr -l C -- class = 110
(int) $0 = 110
(lldb) n
class is: 110.
Process 79429 stopped
* thread #1, queue = 'com.apple.main-thread', stop reason = step over
frame #0: 0x000000010000049c foo`main at foo.c:8
5 {
6 int class = 100;
7 printf("class is: %d.\n", class);
-> 8 return 0;
^
9 }
Target 0: (foo) stopped.
(lldb) expr -l c++ -- class = 120
^
error: declaration of anonymous class must be a definition
warning: declaration does not declare anything
```
That seems useful, does patch break that feature?
