Not just that, but you shouldn't use it at all, rather you can't 
use it!

You might be able to call it, but it won't work as expected 
because strings are not zero-terminated in D, unless the string 
is a literal.

strlen looks for \0, so using it for a string that isn't 
zero-terminated is asking for trouble.
