+Exit the current group or test scope skipping any remaining commands.
+
+Note that \c{exit} is a \i{pseudo-builtin}. In particular, it must be the only
+command in the pipe expression and its standard streams cannot be redirected.
+
+Without any arguments \c{exit} exits the current scope successfully. In this
+case, if exiting a group scope, teardown commands and cleanups are executed
+normally.
+
+If an argument is specified, then \c{exit} exits the current scope and all
+the outer scopes unsuccessfully, as if the \c{exit} command failed. In this
+case the argument must be the diagnostics string describing the error.
