Overhall I think that D was not hard to learn because well 
designed (i.e intuitive).

A few specific points however that I remember

- Certain variant forms of the `is` Expression are not obvious 
(not intuitive), I'm pretty sure I still cant use them without a 
quick look to the specs.

- Operator overloading in certain cases was confusing, I remember 
that for one particular form once I had to use your book instead 
of the official specs (when opSlice and opIndex are combined)

The main difficulty I had is actually not specific to D. It was 
to accept that a GC is OK.
