This is especially useful on nightly, where it works for unsized trait objects.

(Unsized slices cannot be supported with the current design, as there’s no conversion from [T] to dyn Trace: #2 (comment).)

Fixes #72.

Added documentation and comments; how’s this?

(I note that clippy::pedantic has been complaining about missing safety documentation for unsafe trait Trace, which we should probably add at some point.)
