Huh?++

huh?++, or '''huh? plus plus, is an esoteric programming language created by Kevin Friedemann (user:kfriede) based on the huh?''' programming language created by David Catt (user:David.werecat).

Instructions
Like huh?, every file is a valid huh? program. However, huh?++ boasts a 100% failure rate, and doesn't bother to tell you that it doesn't understand your input. Commands are assumed to be too difficult for huh?++ to understand.
