*Actually*, which comes from the BSD shell script /usr/ucb/which. Using it as a usage example would probably be poor, since it did things like "set prompt=""; source $HOME/.cshrc" and other gross kludges. The tcsh builtin is simply "doing it right"; the common bash 'alias which=type' is usually close enough. Given that the script is for invocation by programs, not users, it doesn't *need* to locate builtins...
