Very nice read!!! Thank you!


One "typo?" Chapter 8)

  s/compile/run/

It would be good to say a little more about the '!' ct-parameter

At fist when reading D code coming from ruby (after, 
php,...C++,C, Pascal...),
I thought, that the ! is like in Ruby just an way to distinguish 
between a function modifying the contend or not (compare gsub to 
gsub!) it took sometime before this important bit came clear to 
me.
So just something, like functions in D may have two parameter 
brackets:
One for compile-time and one for run-time parameters:
fun!(ctParam)(rtParam) ... short fun!(cParam)() ... fun!ctparam

Other point:

Showing some more alternative D solutions for the same problem, 
might be a little contest in this thread, just post your shorter 
and better solutions :-)
