Thanks for the elaboration. I might even agree about the typing, even though e.g. `end' requires one keypress more than } for me. But I find that punctuation stands out more. From a practical point of view, I prefer reading Haskell's

  \arguments -> body

to Scheme's

  (lambda (arguments) (body))

because it stands out more. What gives me as the reader an even better hint without getting in the way, is indentation. That's why I prefer that to e.g. curly braces for reading. (Writing, especially in non-programming editors, like a webform, is easier with explicit markers like `end' or } though.)
