I think you might be misreading the assembly – which operating system
are you on? You can only expect to see _d_local_unwind on Windows, Dwarf
EH is implemented differently.
OK, that probably explains it :)
In the first case, where the code can't throw, the exception handling
code is probably not generated at all.
Yes, I see that the compiler likely does the right thing, and I just
implemented a totally useless feature in the face of scope(exit) :)
I was kind of curious though, if it would work!
