hashOf is not guaranteed to produce unique values, so I would not 
advise using it here.

to!string is expensive both at compile time (requires a lot of 
template instantiations) and runtime (needs to allocate memory 
for the string). It will work if you need to hack something 
together quickly, but I would not recommend it for "serious" code.
