That's the sort of thing that makes me think that deprecated should be an
attribute (since, if D attributes ever become anything like Java attributes
like
I hope they do, they can take argument like that).
Regardless, that would be a definite improvement, especially if we end up with
much deprecated in Phobos. I think that up to this point, we've mostly just
made
changes rather than deprecate things. I think that std.contracts is the only
one
that I've seen.
