I was looking for image=? in 2htdp/image but couldn't find it until Alex Knauth mentioned its in BSL but not exposed, is there a reason why its not exposed to the library.

(require lang/imageeq) ;it can be required here
(require 2htdp/image)

but if you need both 2htdp/image and image=? , then it leads to:

. module: identifier already required
  also provided by: lang/imageeq in: image?

You might also be able to get away with just using equal? if putting a prefix or a rename on the require isn't an option.

What I mean is why isn't it just available from the package 2htdp/image? (require (only-in lang/htdp-beginner image=?)) works though so you can close this issue.

I think it is because it is just equal? although the history here is not at my fingertips!
