Very nice work and very much needed!

Found some errors:

- http://dlang-tour.steinsoft.net/tour/basics/2

   * "long, ulong (32 bit)" <= should be "64 bit"

   * "real (depending on platform, 80 bit on Intel x64)" <= 80-bit 
on Intel x86 32-bit, not sure about Intel x86_64 and I think it 
depends.

   * "A conversion between variables of different types is only 
allowed by the compiler if no precision is lost." => except FP 
types. eg: double => float.


I think you have some room to introduce __gshared, I've seen one 
case on IRC with someone not knowing about it and wondering why 
threads read a different value.

You already say that "slices" and "dynamic arrays" are the same 
thing, but I think this need to be put in bold. For the longest 
time I had difficulty to envision the difference between the two 
concepts, but there seems to be none. It happens some D material 
present them separately.
