Or "Omg! D's templates generates all this junk that can only be coped with  
using auto?", hehe.
I remember when I first looked into std.algorithm _without_ any functional  
programming background or reading Andrei's book. It was absolutely  
incomprehensible to me, what these functions like 'filter' could return or  
how I can make use of it. I wanted to put an array into it and get back a  
filtered array. I imagined that the return value must be some obscure  
language internal called a 'Result' and found no other way to use it  
except for wrapping any functions from std.algorithm in another call to  
array(...). Only recently I understood enough of CTFE to recognize that  
the return values are still conventional structs offering an implicit  
interface and no black magic. Now I quite like what is possible with - for  
example - map in one line of code.
