How do I debug my own code ?
If I call (debug (my-function my-argument)) the debugger says that the
object passed as argument to debug is not a condition
Matt,
thanks for your help !

I'm reading the chapter about logic programming in the SICP book.

Is there a library I have to load in order to play with those examples ?
Thanks
