It's about time somebody noticed this!!

Why don't we just expose druntime's core.internal.hash.hashOf() function
somewhere? It's not as though it isn't already in druntime, so the
function is already present in the executable, we just need a public
declaration of it somewhere that users can make use of.

Not to mention, it's already a template function that correctly
calculates the hash of various built-in types.
