First experience with std.algorithm: I had to resort to writing a 'contains' function.

I want you to know that you are not the only one who makes such 
decisions. I have almost the same method, except it returns an index 
value. That is not the only one reason I wanted a std library with clear 
and documented interfaces. Generally I use std library to make writeln, 
thread wrapper around OS, and string conversions. I do not want to use 
std.algorithm.
