macro-happy

I'm still a little too macro-happy these days. Hopefully this phase will pass.


I found a few good references on guidelines for macros:

I can't end this without not posting my little assert macro

  (define-syntax (assert stx)
    (syntax-case stx ()
      [(_ expr)
       (quasisyntax/loc stx
         (unless expr
           (error 'assert (format "~a lineno ~a: ~s failed" 
                                  #,(syntax-source stx)
                                  #,(syntax-line stx)
                                  (quote expr)))))]))
