This strange code - https://run.dlang.io/is/BKgv49 - fails

Switch cases are labels.
But why?
You mean why is it an error? Probably because the compiler
needs to guarantee you are calling the super constructor, and
it can't figure out the flow when it sees labels/loops. Not
that it's always impossible, but it's likely a complication the
compiler devs don't want to deal with.

Why isn't the compiler doing proper flow analysis? Is it that
just no one bothered to implement it?
