Scheme and CL (and Emacs Lisp) have many individual condition types that
do not carry the word "condition". For example, R7RS has "file-error"
and "read-error". By convention, R6RS condition types have names
starting with an ampersand: &warning, &i/o-file-is-read-only, etc. These
are simple and direct names. There are also more abstract ones, but this
shows that fancy names are not a requirement.

I don't see how e.g. &foreign-status would go against the grain.

(Some Lisp systems would say "alien-status" but perhaps that's too cute :)
