This is not supported in 8-bit compatible mode; it's 'turn' that seems to be a problem:
vocabulary { : verb { aliases = [move, pull] } : verb { aliases = [move, push] } : verb { aliases = [move, turn] } }
I've got a feeling that PULL and PUSH are built-in verbs, but I'm not certain. At any rate, you only need one statement:
: verb / aliases = [move, pull, push, turn]
Thank you; It works like this.
