Before Nu version 0.67, Nu used to use CMD.EXE to launch external commands, which meant that the above builtins could be run as an ^external command. As of version 0.67, however, Nu no longer uses CMD.EXE to launch externals, meaning the above builtins cannot be run from within Nu, except for ASSOC, CLS, ECHO, FTYPE, MKLINK, PAUSE, START, VER, and VOL, which are explicitly allowed to be interpreted by CMD if no executable by that name exists.
