Well the diagnostic doesn't print the result of the LHS/RHS:
```
./array.cpp:202:18: error: constexpr variable 'u13' must be initialized by a
constant expression
202 | constexpr bool u13 = pf < pg; // ref-warning {{ordered comparison of
function pointers}}
| ^ ~~~~~~~
./array.cpp:202:27: note: comparison between '&f' and '&g' has unspecified value
202 | constexpr bool u13 = pf < pg; // ref-warning {{ordered comparison of
function pointers}}
| ^
```
I'm not exactly a fan of how the code looks though. I might add a helper
function for this later.
