So it had to be properly defined in the spec and implemented.
Meanwhile we're fighting with the Phobos Typedef and it has way more
problems right now, some of which will likely be unsolvable. Bug

Most of these look approachable, and there are workarounds for the
others. Granted, the UDT can't be made 100% like the old typedef (and
probably that would be bad, too :o)).
* scope: cute and dangerous in equal proportions - great for a movie
character, terrible for language design.
scoped() has its own quirks, for example:

http://d.puremagic.com/issues/show_bug.cgi?id=5115
http://d.puremagic.com/issues/show_bug.cgi?id=10921
And this last bug that was filed (10921) was a bug that was known since 2010:
http://d.puremagic.com/issues/show_bug.cgi?id=5115#c6
So 3 years later, and it's still an issue. I don't even see how Issue
4636 can even be fixed, there's no way for a template in another
module to get private access to the class constructor.

Anyway, we've deprecated old keywords, and introduced half-implemented
library replacements. I don't see how we stand any better today than
we did before.
Library issues are a lot easier to deal with than core language issues.
