Indeed. Like AppleScript, appscript uses some special tricks to allow you to specify the command's direct argument in more than one way, either as 'application.command(directRef)' (the literal form) or as 'directRef.command()' (convenience form; converted to literal form under the hood). What the OP's actually writing is 'directRef.command(anotherDirectRef)', hence the [somewhat cryptic] error.

The Application Commands chapter in the appscript manual has a section on special case behaviours. I'll amend it in the next release to better explain this particular error.

Yup. Or:

a_track = app('Itunes').playlists['Library'].tracks[0]
a_playlist = app('Itunes').playlists['Whatever']
a_track.duplicate(to=a_playlist)
