Currently, the compiler (like @typeName) writes it `fn(...) Type` but zig fmt writes it `fn (...) Type` (notice the space after `fn`). This inconsistency is now resolved and function types are consistently written the zig fmt way. Before this there were more `fn (...) Type` occurrences than `fn(...) Type` already.
