In bugzilla I have asked to disable the implicit conversion enum => base type in an equality test, see:
http://d.puremagic.com/issues/show_bug.cgi?id=3999

In bugzilla I have never asked to disable implicit signed => unsigned casts, I am able to see they are two quite different situations.

I think the implicit conversions from enum => base types are uncommon enough, so they can't introduce too many casts.

If Walter doesn't agree with me (and few other people here) then there's no point in keeping bug 3999 open, it can be closed. Because it's better to fix/change similar things now, when the D2 language is not diffused yet. Later such changes are harder to do.

In bugzilla there are few other things that deserve a similar look. Those changes can't be done all at the same time, but the decision can be taken in a short enough time, and it's better to think about them now.

Bye and thank you for your attention,
