First problem: in your example, foo doesn't return a string. It would 
try to print "some stuff which..." to whatever output is being used (on 
a webserver, the socket). So using <%= tags aren't nessesary.

Second problem: because of the way that output is managed, the scope 
inside foo() can't see the output handler. Therefore, you get an error.

Solution:

#######   code:

-- define foo
<% foo = lambda do %>
   some stuff which should be displayed
<% end %>
-- now, test foo:
<% foo.call %>
-- test foo again:
<% foo[] %>

#######   output:

-- define foo

-- now, test foo:

   some stuff which should be displayed

-- test foo again:

   some stuff which should be displayed
