Here is a small test file with these two solutions. As you can see
from running the file, the "lambda" solution does not work. The
"method definition" works fine (but I loose all the local variables in
the definition.

Another solution would be to capture binding before method definition
and pass it inside the method (but this looks a lot like a block.

To the clever minds out there: is there a way to fix the first
"lambda" solution ?

<% a = lambda do |var| %><<%= var.name %>>
<% var.children.each do |var2| %><%= a.call(var2) %><% end %></<%= var.name %>>
<% end %>
-------------
<% a.call(data) %>
( see pastie above for data format )
