Really? Cool... Havnt been following but thought Apple were rejecting REPL applications.

You just can't load code from external sources. I am not familiar with iScheme, but Pixie Scheme III is a scheme REPL and when you quit the app your work is gone... You can cut and paste into another app (notes or something that will sync with dropbox) but according to Apple's rules if you interpret code you can only run code you include yourself or that which is entered by the user.

There's ones for BASIC and Lua too, as well as JS/HTML/CSS previewers.
