Re: loops

[Hans Aberg]

In the one variation, you let your parser to write say some C-code,  
which is then compiled, the resulting program executing the loop. In  
the other, you write a class "loop" which can hold a sequence of  
commands, and then write a function "evaluate()", which can execute  
the commands after a "loop" object has been built.
