I am on day 1 hour 1 of teaching myself Scheme. Needless to say, I don't understand anything. So I'm reading The Little Schemer and using this thing:
as an interpreter.
I need to use '
in for example
(atom? 'turkey)
to avoid an "undefined variable" error. The '
, according to the book, is a Common Lisp thing.
I have two questions:
Is the interpreter I mentioned above a good one? Can you recommend another? I need one that will go well with The Little Schemer.
What is
'
?
