See constant-initialized vs. constant initialization.

These terms mean something completely different, but they share the same name, with the only difference between them being hyphenation. This has idiotic consequences:

void foo() {
    // x is constant-initialized
    // constant initialization does not take place
    int x = 0;
}

A user of the language, or an author of a paragraph in the standard could completely change the meaning of a paragraph by forgetting a hyphen, or accidentally inserting one.
