maybe this question is a little subtile, however, so far, I don't know how to solve it:
suppose I reuse the Expression concept in my own language as some child of some custom concept for being able to define constraints like a > 0 && b > 0 in my language. Now, during generation I simply want to print the expression to the output, i.e.: a > 0 && b >0, for the above example. Unfortunately, this somehow does not happen, despite what I try (getPresentation() and the like), I only get && for the running example (a > 0 && b > 0). Is there any way to easily pretty-print an Expression or can it only be done by iterating the expression (probably) recursively and creating the presentation (i.e.: a string) child by child?
Thanks in advance,
