Using IES for mixins

[Steven Schveighoffer]

Just wrote a quick blog post on this. Is there any interest in 
having this in druntime?

Another option, which we were discussing at extended beerconf 
(yes, it's still going on, though it's pretty lonely right now) 
is to just have mixin accept IES as-is.
