However, in the process of implementing and running the syntax check on existing objects, I have found examples of the following:
refine { <expression> } refine { <expression> }
See, for example, AS7574 in the RADB. Unfortunately, such expressions are invalid in the lastest RPSLng draft. Are such expressions semantically identical to nested refines/excepts? Should both this form and the nested form be allowed. I have come up with a minor modification to the -04 syntax that would allow both, but I'm not sure if it is a good idea or not.
I use that sort of construct all the time so it better continue to exist! See AS2764 (where I used to work) and AS7575 (my latest effort). RADB's reformatting makes it less obvious but it is a cascading refine. Mark.
