The reader-site test of the shell guard (unknownsites_test.go) detects a function that reads a word dash only by the shapes the package uses today (strings.HasPrefix with a dash literal, a comparison with a dash); a reader written as a switch on the first byte, strings.IndexByte, bytes.HasPrefix or a named dash constant would pass unlisted (review4-guard finding 5).

Grounds

• pursued: a reader of a word's dash written in any spelling is found and must be listed; a spelling the meta-test feeds it that it misses would show it wrong
