Currently *above* from 2htdp/image requires at least two arguments. I.e. procedure
(above<file:///Applications/Racket%20v5.3.6/doc/teachpack/2htdpimage.html?q=define#%28def._%28%28lib._2htdp%2Fimage..rkt%29._above%29%29> i1 i2 is ...) → image?<file:///Applications/Racket%20v5.3.6/doc/teachpack/2htdpimage.html?q=define#%28def._%28%28lib._2htdp%2Fimage..rkt%29._image~3f%29%29> Recently I have been using an idiom where I stack a list of one or more images. I.e. (apply above list-of-images) I have a workaround, but it seems to me that a more tolerant "above" -- which acts as an identity when passed a single image -- would be an improvement to the library. Similarly for beside, etc. Dan
