ugly and/or useless features in the language.

Well, I don't like magic constructs in the language like the type 
of AliasSeq you can't touch.

But the more general problem in D are not features per se, but 
how they are composed of.
For instance: Why no AST macros instead of string mixins, 
templates, mixin templates and alias?
All these forms could be special ast macros.

Structs are nice but at the same time awful to use because they 
are incompatible with interfaces and classes, I hope this will 
change to some extent, but I think it wouldn't be that smooth.

Being multi-paradigmatic seems nice at a first sight, but which 
paradigm should your standard library and other frameworks 
follow? Providing all paradigms at once make your frameworks 
redundant and bloated, so you just follow one which is most of 
the time not OOP.
This is the same problematic with custom memory containers.

I wish we would only use structs as ref/value types with the 
ability to box them to interfaces automatically increasing 
compatibility between libraries to a large extent.
