You have to build a "closure", that can be executed later, building 
it directly in the actions, in terms of code that can executed after 
the syntactic termination of the loop. This code can be binary, or an 
output in some other language that can be compiled and executed 
later. Most do it directly, by hand, perhaps invoking M4, Guile, or 
something, as an aid if the output is any other language. Just a few 
days ago, there has come to my attention the tool 
<http://www.codeworker.org>, probably useful for more advanced things.
