I'd actually argue the opposite. I think that they should be the normal behavior, and if you're getting a ton of warnings, I'd argue that you have a ton of problems that need fixing. dmd is generally good about not having useless warnings. Now, with the current version of github, it unfortunately seems to spit out a bunch of duplicate messages for the same error/warning with templates in a number of cases, and _that_ should be fixed, but the warnings themselves are generally solid and indicators of a real problem. And as I've expressed in the past, I think that -property is very much doing the right thing and that not strictly enforcing properties is horrible, but obivously we're in disagreement on that. - Jonathan M Davis
