Re: [Haskell-cafe] Small syntax question

      The problem is that the semicolon after "let a = 3" is consumed as part 
of the let-declaration.
To make sure that the semicolon is not parsed as part of the let, you 
need to indent it less than the variable "a".
For example:

module Main where
main = do {
	let a = 3
	; return ();
};

Why isn't this one [valid]?
module Main where
main = do {
  let a = 3;
  return ();
};
