I never really expected this to happen but it did: Koopa, my little hobby Cobol parser, found some extra developers!
The Koopa team* welcomes Simon Sobisch and Luís Rodrigues. Simon has been very helpful in detecting bugs and suggesting improvements. In fact I had to start making use of the bug tracker just to keep up. :-) Meanwhile Luís offered a major contribution to the grammar, and is now frequently adding more and more directly to the code. Every commit he makes feels like a little present I get to open. :-)
So to both of them a big thank you!
* I.e., me. :-)
