I think imp and phk are after different things.  phk wants a tool
written in Rust that be installed from ports and interpret test cases
defined in src.  That's similar to the fsx tests, which I'm planning
to add to src once the package builder catches up.  But imp wants test
cases that are actually written in Rust and which live in src, to test
his external toolchain proposal.  That's very different.  It's an
unusual requirement.  Off hand I can't think of many subsystems that
are a good match for a test suite like that.  ypclnt(3) might be one.
