Sure, but you lose the clarity of errors. The error wasn't in `comptime unreachable` but in `inline .a .b .c`.

I disagree, I would say the error is in "comptime unreachable" or maybe the whole "switch (ab)".

[Ygg2]

`comptime unreachable` isn't the underlying cause and not the place you should fix in this case. A good error tells you what caused it, and where to fix it.

Adding a new case is legitimate, failing to handle it (by reaching unreachable) is an error.
