- Null terminated strings without length validation

- No bounds checking by default

- Implicit conversions between enumerations and numeric types

- Lack on any sort of namespacing mechanism

- Use of explicit pointers for out parameters

> * Worst features (in your opinion) in D

- inconsistent tag soup, e.g. @safe vs pure, and the amount that 
almost feels like coding with Spring annotations

- the __ prefixes for some runtime stuff like __traits

- chasing the next computing fad while trying to find out the 
target audience

> * Features you'd like to see in D

- basically all the WIP stuff actually finalized before anything 
new gets started

- safe by default (well I can still dream, until then @safe: at 
the top of each module)

- a richer ecosystem, C++, Java and C# aren't the same ones as 
when Andrei's book got published.
