Thanks for the suggestion. Looks like we currently use 2.3.4.

This still wouldn't solve the problem because now the user would need to call something like  getattr(wbt, "exec")(<args>) instead of wbt.exec(<args>) like all the other commands.

I think the easiest thing for me to do would be to just change the command name from exec to something else.
