As an observation, I always found ruby's "then" to be a rather 
superfluous non-keyword; that is,

  if a == b then
    ...
  end

  if a == b
    ... same
  end

  if a == b then ...; end

  if a == b; ... same; end

So a possible (but highly incompatible) approach would be for "then" to 
introduce a single-line block, e.g.

  if a == b then puts "hello"; puts "world"    # end implied

  if a == b
    puts "hello"
    puts "world"
  end

It could also be used, although less obviously, in other constructs:

  while !a.empty? then puts a.shift

I'm not sure what 'then' followed immediately by newline should do.

Anyway, this is just an idle thought, as it would break lots of things.
