- templates, meaning a lot of code is generated only at compile 
time, meaning D will never have the IDE support and refactoring 
support as languages such as Java/C# have. Also bad error 
messages when things go wrong.

- multiple personality disorder memory management - one day D is 
a GC language, then it's actually going away from GC towards ref 
counting, then it's actually towards a borrow checker, hard to 
keep up and the ecosystem suffers

- many features interact with each other in weird ways. Just look 
at any recent language improvement DIP, those are always 
postponed because the code in some obscure scenario breaks
