What I really would be curious about is if in most D code, you see a
lot more default: break; than default: assert(0);
I just did a quick git-grep on the compiler source (not D, but all
switches do have a default thanks to the d port)
With 707 "default:"s 68 had a break on either the same or next line, and
249 had an assert(0).
On phobos I get 22 assert(0)s vs 10 breaks with 147 defaults
With druntime i get 24 assert(0)s + 5 error();s vs 11 breaks with 64
defaults.
Good data, but I was more thinking of people who use D, not the core
language. The core language's developers have different behaviors than
standard users. I'm not dismissing this data, but I would like to see more
application statistics.
Another interesting data point would be whether any of those asserts were
inserted after the language deprecated missing defaults, or if they
existed beforehand.
One thing that is nice is how asserts are supported in D. It makes this a
much easier decision.
