(let ((there be)) lisp)

I keep having lots of fun with hascheme. In the last couple of
days, I implemented quite a few things. Mostly they are syntax
sugar for things you could already do in HAS, or useful procedures
needed for my basic interpreter testing.

• Perl side
  
  
  
  • (define (fun args) body) is now accepted as an alternative way
    to declare procedures.
    
  
  
  • (let) implemented. These bindings for local vars are just sintactic sugar for
    what you'd write in perl:
    sub { my $a=shift; … }->(initial_val)
    
    


• Scheme side
  Reread the 'Why functional programming matters' paper, and implemented:
  
  
  • make-counter, foldr
    
  
  
  • append, sum-list, length, map . All are specific cases of the previous
    
    

Reading chapter 4 of our MIT beloved book, I saw the next step, making a lazy
interpreter from this Half Assed one.

Ah, the repo
