Description

This was raised by @ahl in the following context:

          maybe change `internal_error`?

Maybe these should accept impl ToString ? or AsRef<str>

I have often found myself creating an internal error by calling foo.to_string() here. That causes an allocation at the call site, passes a reference from which a new allocation is made, and then throws away the original. It might be nice to take something like impl ToString and call to_string() internally.

Research direction

Start by locating Omicron's Error::internal_error definition and reviewing its call sites, especially those that call foo.to_string() before passing the value. Determine how the error can accept a more general string-convertible input, then confirm that callers avoid the unnecessary allocation and existing error behavior remains intact.
