I think what this test actually tests is whether `getattr` was called on
`conf.lib` with everything that's in FUNCTION_LIST, i.e. it test
`register_function` and code around it:
```python
import ctypes
from pprint import pprint
lib =
ctypes.cdll.LoadLibrary("/home/user/endill/ramdisk/llvm-build/lib/libclang.so")
print("--- before getattr")
pprint(vars(lib))
getattr(lib, "clang_createIndex")
print("--- after getattr")
pprint(vars(lib))
```
outputs:
```
--- before getattr
{'_FuncPtr': <class 'ctypes.CDLL.__init__.<locals>._FuncPtr'>,
'_handle': 906416256,
'_name': '/home/user/endill/ramdisk/llvm-build/lib/libclang.so'}
--- after getattr
{'_FuncPtr': <class 'ctypes.CDLL.__init__.<locals>._FuncPtr'>,
'_handle': 906416256,
'_name': '/home/user/endill/ramdisk/llvm-build/lib/libclang.so',
'clang_createIndex': <_FuncPtr object at 0x7f8296567dd0>}
```
So for purposes of testing for completeness of `FUNCTION_LIST`, this is an echo
chamber.
I'm looking into other ways to test that.
