The thing that worries me is that foo:: syntax and external helper
interface was invented by Daniel Barkalow primarily because he
wanted to allow things that do *not* fit in that URL-like scheme,
for example see:

Yes.  A blind guess that fails spectacularly is far worse than an
outright rejection that is cautious.
