Can't compile with 1.21.0-nightly

[ghost]

Dependencies all build fine, but plex itself fails with a bunch of rustc errors.

Using a git dependency in Cargo.toml knocks it down to four errors:

I've fixed the compile errors, but the example program still doesn't work because of some annoying macro stuff. I'll see if I can fix those for now too. I keep talking about it, but I really do need to rewrite this to use the new token-based proc macro system.
