It is not about putting the *Boost library* into release mode,
but about compiling your code with release settings, usually
implying that the optimizer is used among several other
settings oriented toards making the resulting binary code
faster and lighter.

Some hash value has to be associated, as the element is
to be inserted anywhere into the index. Your mechanism
is a good compromise.
