Talk:Write Yourself a Scheme in 48 Hours/Building a REPL

The repl doesn't allow me to correct input with backspace (much less editing it with the arrow keys, hitting C-p for previous input, etc). Is there an easy way to add readline functionality to this?


 * See the readline package, the editline package, or the Shellac package.
 * Alternatively, you can just use rlwrap to quickly get readline functionality without changing your code

Very weak REPL
Although this is a wonderful wikibook in general, I have to say that this REPL is to all intents and purposes utterly useless, because it will only parse Scheme expressions that fit entirely on one line.

Obsolete provision?
