I find that when I am building a box pp file by cutting and pasting from the -generated.pp file I very frequently screw up the comma separation because I might paste at the end with a comma, then I have to remove the comma from the new last line and add it to the old last line.

It seems like it shouldn’t be too hard to allow a trailing comma thus making copy and paste between files a lot easier.

This issue definitely contributes to a level of frustration when using Spoofax … yet should be fairly easy to fix.

Comma is a separator, like it is in function parameter lists. That is the syntax. Editor should help you find that.
