Can it be a matter of taste if the key word "unsigned" should be repeated
in such an use case?

How do involved software designers and developers prefer to achieve
data type consistency here?

Which kind of naming convention will get priority?

Would you like to extend another evolving script for the semantic patch language?


I imagine that the general issue around the exception handling will cause
too many software development challenges to tackle them "at once".
